Description
Advances in the processing of materials on a micro-scale have led to the development and introduction of devices that employ very small needles – Microneedles – that deliver drugs by mechanically perforating the outer skin layer and allowing for transdermal absorption of the active compound. These processing techniques incorporate one or more technologies that enable the precise machining, extrusion, casting, and/or forming of from one to an array or grid of microneedles.
