Fabrication and characterization of gold coated hollow silicon microneedle array for drug delivery
Fabrication method for an array of hollow tapered Si microneedles is presented. Si microneedles biocompatibility is increased by coating Ti &Au. The breaking force of fabricated microneedles is 10 times above the skin resistive force. Flow rate variation through microneedles with respect to different inlet pressure is studied.
