AFM is a complimentary technique to SEM. Both can provide nanometer resolution images, but their different mechanisms (phyiscal probing vs electron beam) means they have different characteristics. AFM excels in precise heightmaps of the sample, easy scanning (no vacuum, no metal coating) and a diverse range of related techniques. SEM offers high depth-of-field and a very large field of view, which makes it easy to get a broad overview of a sample and then zoom in. Labs often use both in research because they compliment each other's strengths.

That's actually a really good way to grab attention, especially with results that good I want to know how it was achieved :D
This guy has a PhD degree
I agree
That alone got me to sub
Super absolute legend
The best part. Is that Historically humanity in the past has poked things with sticks to try and understand them. But in the present day we still do, the stick has just become a whole lot cooler.
We never imagined textures could be so quantified. Our ancestors knew nothing of the micro world, they couldn't even conceive of a stick as small as a nanometer and moving so quickly.
@@SpeakerWiggin49 that’s not the point, the point is our ancestors poked things with sticks to try and understand them just like we’re doing now with the microscopic world
@Stellvia Hoenheim ..... Pls stop.
Come here. We are experimenting on people.
-How do you experiment on people?
We stick things in them.
- Are you from the Biology Lab?
What's a bilogee lab?
They are a lot cooler for sure!!! And much much much smaller 😂
I've been retired some 12 years now, but back in the '90s I lead a team to select and purchase an AFM. I then supported it (and its Windows 3.1 interface) and trained users. Your model is excellent.
Back in the 90's I was working with one of my profs building these. stm actually. iirc, there were doubts as to whether they were actually showing the images they said they were...
Hey we're waiting for somebody to prove that about our own perceptions? Are we really hearing what we think were hearing are we really seeing what we think we're seeing how do you know?
Can we talk about how he literally built a scanning microscope for demonstration purposes?
macroscope :o
@@deepspacemachines lol true
This is a completely different lifestyle of focus. I thought my KD in Cod was good... this man is helping solve wonders of the world.
@d3adsoulja i meant the macroscopic one
I don't think it is a "scanning microscope." I think it's actually a "probing macroscope."
Amazing! As a technician in a physical lab i applaud you for the great explanation, and the macroscale AFM makes it so much clearer for everyone!
@Stellvia Hoenheim I have basic knowledge of AFM, i am not an expert. (I learned new things)
My thanks is for the time/effort spend on the research, explanation and rebuilding a 3d printer to AFM to teach people the principle.
Love this so much, its like the most basic nature of humanity.
"What the fuck is this? lets poke with a stick" thoughts stand the test of time to the fricking atom
YES!! That and "let's smash these two things together to see what flies out"
@@199NickYT you forgot "lets burn these things to see what happens"
@@theman13532 Or even "let's poke it with a (nanoscopic) stick"
Holy shit that pcb is crazy, those little flexures are really cool
Right?! Miracle of engineering, it's wild that these things are possible at all.
@Stellvia Hoenheim Stellvia of the Universe
As a PhD Student in MEMS technology the chip a 7:18 just put me in awe.
I know how complex the mechanics of the "simple actuation" I want to achieve is. This thing with x/y/z controlled motion is just beyond and stunning to see in almost exclusive silicon.
Edit: 13:06 blew me away even more! One can still see the point the the "arm" was etched free from the surface, amazing!
Pretty wild, right? It's amazing what MEMS engineering can do these days! IIRC, the actuators are thermal bimorph actuators (instead of electrostatic comb, which is what I assumed at first), which is just super cool :)
Atomic force microscopy is one of my favorite microscopy techniques, just because it can see down to nanometer resolution, give quantitative data in the Z direction, and the sample does not needs to be in a vacuum. compared to scanning electron microscopy, which requires the sample to be in vacuum, does not see in 3d or give quantitive data in the Z direction.
Atomic force microscopes are just so cool
also scanning electron microscope damages the sample because the electrons (since they are accelerated to a somewhat high speed) can hit the electrons in the atoms of the sample itself and affect the valence bonding in the chemical elements under inspection. So, if you making some custom integrated circuit for a client, and you want to verify if it is ok (quality test), you can't use electron microscope since it will introduce defects in the product
@@absolute___zero That’s true too
It’s really incredible we get to have complete MEMS AFMs in 2021. Seems like this came a bit early
Nah, 2021 owes us.
2021? We should have halfway mature universal assemblers.
@@ExtantFrodo2 idk man transistors aren’t even 100 years old yet. Micro fabrication is still very new
@@andrewphillip8432 Present day technology is sufficient for individuals to build personal spacecraft as well as orbiting habitats and factories with all necessary life support systems and communications. Yet almost no one understands the power and capabilities of the programmable femto-second quantum cascade laser array which can not only implement catalytic chemical restructuring on demand but molecular positioning and orientation as well for nano-assembly.
@@ExtantFrodo2 Personal spacecraft?
I hear on good authority that "Tapping on atoms with a very sharp stick" is also a highly technical term.
Great video, easy enough to follow even though I had no idea about your field. Thanks for sharing.
what i really like about your channel right now is that while it hasn't exploded yet, you have enough time to reply to semi-sensible comments that we leave, which i'm pretty sure will not be the case once it takes off :)
Well, if the channel ever does take off in a big way, I'll still try. I like interacting with folks in the comments, I've learned a ton that way! There are _a lot_ of super knowledgeable folks here :)

*Addendum*
- More footage of the probe scanning here: ruclips.net/video/m0UK7LVSZ8g/видео.html
- If I mispoke, leave a comment and I'll add to this addendum! I'm new to AFM :)
- Sorry for the "glow". Some poor life choices were made while filming (fogger, for cInEmAtIc haze) and made my life hell in editing. Lessons were learned 🙃
- There are _many_ types of scanning probe techniques, I'm only describing a very small handful of techniques for topographic information. I might cover other techniques in the future, there are dozens! There are equally many variations of topographic AFM itself, and each manufacturer has their own special sauce, so my comments are just general statements :)
- Scans were post-processed in Gwyddion, and the 3D animations done in Blender
- The Macro-AFM architecture is: arduino driving voice coil and measuring back-EMF, a grbl controller handling stepper motors, Rust program talking to both of those and providing a browser-based UI
- I should have elaborated on spatial resolution more: the final resolution you get is a combination of tip radius and surface geometry. A wide tip (100nm) can still get you high precision (few nm) spatial resolution if the surface is very flat and the features are not high aspect ratio. But high aspect ratio like nanoparticles or trenches will require a sharper tip that itself has a high aspect ratio, so that the tip can access the internal geometry. So spatial resolution is variable depending on what tips you load and what the sample looks like
- Gage block is a cheapo import from Shars, so I'm not sure if this is representative of precision ground surfaces in general, or just cheaply ground ones :)
Nice Blender work! Any reason you stuck with the classic yet boring AFM colormap?
@@MichaelWatersJ No particular reason :) Any suggestions for better color schemes? Definitely new to color maps in general, not sure what the best strategy is
JET map for the win
Do you think it'd be possible to combine this with something like the Open Flexture Stage to slightly move the object over to rescan and expand the area?
It doesn't need to do this super accurately as long as there is some overlap since that could be used to stitch the scans together automatically.
Awesome video! Only thing to note is that there actually are quite a lot of modes that use contact mode as the base! It does dull the tip more, but with a proper calibration you can limit the forces applied to the surface. Some interesting contact mode applications are like conductive AFM (CAFM), piezo force (PFM), scanning capacitance (SCM) and more!
try it in a CD, we should be able to see the data in the grooves.
you can see that with a regular microscope
Cds are covered in plastic, you can't get to the pits that are in the foil.
@@milothedestroyerify you can remove the foil.
DUDE! you have the best toys, so jelly. Ill just go back to my resin printing corner and cry now. lol
@Stellvia Hoenheim Will pocket change do? I have about 3.50
That's basically a vinyl record player in atomic scale. And I liked how that image gauge block surface resembles Mars surface. I mean, i know they just choose to use that color palette for images but i think it's worth to think about the surface detail/mass ratios of both Mars and gauge blocks.
This is incredible. Imagine how cheap it could be if it was mass-produced
Honestly I can’t think of a single case in my life where I would need this but it’s still cool information.
Ps: awesome deal, maybe unorthodox but a sweet deal
As a private person there isn't really a need aside from curiosity. But it is absolutely a marvelous research tool.
For the sake of science, just the fact that we now know something we didn't before is valuable enough
“Glompy” is a perfectly cromulent word
So i've had that project in my mind for a while.
A geometry scanner to scan complex surfaces in a more or less automated way.
Mechanically like a 3d printer, but with a probe instead of a hotend.
Nothing extra fancy, all i want is .5mm of resolution on each axis.
Guess now i finally have the inspiration for the probe design.
Great stuff!
Everyone: You can't see shit on the atom level cuz it's so small.
Science: Hold my beer.
once we're doing lithography in the angstrom range maybe we will?
Still waiting for those atomic shots....
That gauge block surface really put the resolution into perspective for me. Unbelievable. It looks like the surface of mars, not some of machining's most finely surfaced measuring tools.
That was amazing. Not what I expected.
that macroscale AFM was amazing! This is quickly becoming one of my favorite channels, unique, very well explained and filmed topics.
This is a very good intro to the SPM world, amazing! One quick note, AFM cantilevers don't have a mirror glued on top, instead they might be coated with a metal, like aluminum and gold for certain applications, like AFM imaging in liquid. Cheers!
Whoops, good point! I was watching a lecture on the origins of STM/AFM and "glued on top" got stuck in my head haha. AFM in liquid is pretty wild!
The Macro FM is amazing!!! I did not expect such a great result
Me either! Was honestly shocked how nice it came out, especially after the meh confocal results :)
*Pokes atom with*
*Accidentally splits atom*
“FUCK”
With just one atom, the answer would be, not a lot would happen. In fact with atoms up to the mass of Iron, it actually takes energy to split it. But even with a heavier atom, the amount of energy released from just one atom is so small, my guess is you won't notice anything.
All of this of course just hypothetically assuming it would even be possible to split an atom, by just tapping on it. In reality, that would be impossible to do with something like this. Atoms are tough little guys, with really strong nuclear forces protecting their integrity.
In this scenario, I guess it would be akin to trying to open a bank vault, by blowing on it through a straw. 🤣🤣🤣
@@mierbeuker8148 Wow. You must be a blast at parties. Mansplaining the technical feasibility of every joke. 🤣

@@mierbeuker8148 I'm worried about ya man
Great stuff, I really enjoyed this! I was wondering, the samples you showed are pretty flat and parallel. How does it handle large height differences or things like surface tilt?
Depends on how large the height differences are :) So the max Z resolution is 10 microns. If it encounters something larger than that the probe will bottom out/crash, or just start oscillating in free-air no longer touching the surface (like if travelling over a hole). The cantilever is actually pretty soft and flexible so it's unlikely to damage the probe unless you run it into a _really_ large feature which would be noticeable from the microscope. It'll just stop recording data because the oscillation is basically halted. There are also settings which control the size of the oscillation... I usually turn that up when scanning a new sample because it allows you to clear larger objects. Once you're sure the section is "safe" you can turn it down a little, which gives better resolution.
There's usually some amount of tilt in the scans (due to angle of probe, and the stage not being perfectly parallel) which is corrected when post-processing the data. Different methods to level the image (3 point triangle, intersecting lines, polynomial, etc). If there is extreme tilt it'll be similar to running into large features, at one side of the scan you may bottom out or start scanning air. But OTOH, at a 20um scale even uneven surfaces end up being pretty flat... i was able to scan part of a fly wing for example.
@@BreakingTaps Thanks Zach for this elaborate answer. Sounds like this is a really interesting tool, for example also for layer thickness measurements. I will definitely be checking out this product!
@@HuygensOptics No problem, feel free to ping if you have questions! I didn't get into it in the video, but they have different types of probes: sharp DLC tips and less-sharp wedge tips. The wedges are designed specifically for things like thin-film thickness testing since you don't need the high aspect ratio. Apparently last a really long time and are cheaper. I'm going to be doing some thin film testing in the near future, will let you know how it goes :)
Dude your channel is just awesome. This is going to get so much attention from so many huge RUclipsrs and science lovers alike. I hope you continue down the path of DIY optical tools also. The community needs a well-designed DIY spectrometer, Along with so many other pieces of DIY optical test equipment and scientific apparatus! I think you’re just the man for the job!
Your last few videos have me so excited about the possibilities!
That is one of the coolest tools I’ve seen… & the scans are so quick. 🤯
For real. I work on a nearly 20 year old system at work and it takes around 8 minutes per scan 😂
Very cool indeed! I just finished a very similar project at university. We made our own Scanning Tunnelling Microscope! Uses most of the same principles, but instead of tapping on the surface, you move a very sharp probe about an atom away from the surface. Then when a small voltage between the probe and the sample is applied, a magical current appear that is extremely distance sensitive. Our goal was to see atoms, so a micrometer is pretty huge in my brain currently :)
Goodness, now that is definitely brain breaking. Very cool!
@@BreakingTaps It is a bit confusing the difference between "making contact" and "not making contact", as "physical contact" is a remote interaction between fields, so maybe what is meant by "contact" is when the tip is close enough to produce phonons and potentially exchanging atoms, or rearranging them on the surface, hence potentially causing wear, sticking the needle to the surface, cross-contamination and change in topography?
@@_John_P Hehe good eye, I definitely glossed over that (well, I recorded a bunch trying to explain, but it was confusing and long so got cut). And looks like I technically mispoke in the final cut as well. So my understanding is that "contact" mode AFM relies on the very-close range repulsive forces between the tip and the surface. I believe this repulsive force starts just a few angstroms above the surface, and is why the cantilever is very soft so as to prevent damaging the surface (or tip) too much as they are strongly shoving on each other at that point. The so-called "non-contact" AFM relies on attractive forces at a longer distance, and measures how the attraction to the surface changes the resonance of the cantilever. I believe non-contact cantilevers are much stiffer to prevent them from being pulled down to the surface, and typically have much more sensitive amplifiers to detect the small attractive force.
But yeah, you're totally right: all the forces are remote and nothing is _really_ in contact once you get small enough :)
This is just absurd. The production quality and depth you go into on your videos never ceases to amaze me. Absolutely stunning.
This video is hecking awesome!
Props to ICSpi to working with you and providing you with this microscope!
It’s a shame they too operate on the “request for quote” pricing model. Look I don’t care if your product cost 1k, 10k, 1M, or 10M just list the damn price, whatever it is.

Thanks for your transparency. It improves the rest of this very cool video. Looks like a lot of fun!
Wow, this is amazing stuff! Is AFM only for examining rigid materials, or would it also work on cells, viruses, etc?
AFM can do cells, proteins, DNA, etc! The cantilever is actually very "soft" (although the tip is quite hard) so it will happily scan other soft things like cells or polymers. Mine can only do dry materials so I would have to dry/fix cells to make it work (on the todo list!), but there are other AFMs that specialize in wet environments, like for alive cell cultures. There are even variants that can record the "adhesion" force, and it's used to help differentiate proteins on the surface of cells, since different proteins are more or less "sticky" than the surrounding cell membrane.
There's a sorta-classic AFM experiment that looks at DNA which I might try some day. It's supposed to be pretty tough, but the results are neat when it works :)
@@BreakingTaps Cool! Thanks for the detailed explanation - very deep subject.
I find it odd how im a high-school drop out and i find myself watching videos like this.
It also crazy how small that probe is.
Dropping out means the system has failed you. Not the other way around. It's not a testament to your character. Plenty of legendary thinkers have been fed up with or been failed by the system. If you're curious and rigorous then you're a scientist.
Super inspiring work! The "janky" prototype was actually my favorite part of the video! It made the concept very clear (you can't see a MEMS device working!)
"Glompy" I see you are also a person of Science. (:
WOW! That is *amazing* ! Excellent explainer, the “macro AFM” is great. I learned a lot; I’d always assumed that AFMs were measuring some sort of chemical-type interaction force. They were somewhat conflated in my mind with STMs (scanning tunneling microscopes). I’m **intensely** envious of (a) all your gear but (b) especially your new pro-level AFM. (Brilliant tech; when I saw your macro AFM, I immediately thought that flexures would be a great way to do the x/y movement, then saw that that’s exactly what the ICSPI unit uses, only built with MEMS technology. I wonder if I could 3D print a platform to carry the probe, using flexures? - And also wonder what the ultimate limits might be of your Macro AFM approach.
==> I know they only work on a “request a quote” basis, but *is there any way you could get ICSPI to let you tell us what the overall range of prices is* for the model you have? I assume there are a lot of different configurations, so likely a broad range of prices, but maybe they’d let you tell us the general range? I doubt I’d remotely be able to afford one, but would love to know I’d it’d ever be a possibility.
(I used a mini-SEM in college for semiconductor research I was doing at the time; it was the most fun instrument I’ve ever used 😁)

I love the RUclips algorithm, it has lead me to some of the most awesome channels like yours, the summer of maths exposition was awesome. Thought emporium, and some other channel that speaks about Optics. I can't wait to graduate to start doing some experiments in my free time
You, my friend, is frickin underrated! And this is driving me nuts! 😭😭
There's a bunch of really cool new types of AFMs that also have characterization like the nanoIR from bruker. The same ir peaks seen with an ftir also induce a greater volume change than other wavelengths. The AFM tip detects this change in the surface. You can get 10-20nm characterization resolution and it is very surface sensitive with a penetration of just a few nm. There's also a nano-raman and a nano-ftir.
This is ABSOLUTELY FREAKING COOL!!!
