Coaxial Electrospinning Could be the Future of Wound-dressing

‪@sprucescience‬
In this video, we introduce a coaxial electrospinner and its spinneret with two concentric needles, which has exciting potential for targeted drug delivery in wound dressings. We demonstrate how to use the coaxial electrospinner to create electrospun fiber mats with red markers, using a solution of PVP polymer and red ink. The electrospinning process is driven by an intense electric field and creates unique and functional materials. We also discuss the benefits of using PVP in the electrospinning process, including its versatility, heat resistance, adhesive properties, and non-toxicity. The video includes an overview of the hardware and a step-by-step demonstration of the electrospinning process, as well as the final results. Get ready to see the magic of electrospinning in action!

It is very unusual to make device first and then think about how to apply it to real-world tasks.
Such approach is risky, but I like it for some reason.
I hope that your device will make our world better eventually.

How about mounting the spray need assembly inside a large torus/short cylinder, and spinning that around the collector? Direct application of the fibers to an unmoving wound would be possible. A cheap(ish) testbed could be made from a toroid core transformer winding machine, perhaps.

Very clear demonstration
But why you didn't mix the two solutions in one syringe from the first step? Why use separate syringes and then use coaxial spinneret if what I desire is mixing them into one nanofiber at the end?? What difference would it make? And if so could you please design an experiment please? Electrospinning is my thesis subject!

If you spin horizontally instead of vertically you will not get splatter and drips.
