Based on the adhesive abilities of beetle's feet, Chen-Yi Tsai and Cheng-Chung Change created a new drug delivery patch that has the ability to deliver birth control, treat burns, help with Parkinson's and hyperactivity, and also deliver nicotine. These transdermal patches are capable of reducing side effects such as stomach irritation and are also better at providing consistent drug levels in the body than oral and intravenous administration. After observing the beetle's feet, the scientists mimicked the Van der Waal's and capillary forces to create a micropillar patch that releases drugs in a controlled manner!
What's different about this patch is that it won't irritate the skin, can be used repeatedly, and is breathable unlike the current drug patches. This new invention is made out of biocompatible silicone materials that are breathable and reusable. Although the adhesive properties are strong, the patch is still easy to remove and can release different anti-inflammatory drugs for several days. More tests still need to be done, but hopefully this new development will be out in stores soon!
