Fabrication and testing analysis of tapered silicon microneedles for drug delivery applications
Tapered silicon microneedles are fabricated by an improved cutting method. Force testing about these microneedles indicates that they pierced into skins easily. A 77 microneedles patch is selected to be employed to experiment drug delivery. The permeation of calcein through skins can be obviously improved by this patch.
