Biodegradable Porous Microneedles for an Electric Skin Patch. Issue 9 (15th September 2021) - Abe, Hiroya
Abstract : BIODEGRADABLE MICRONEEDLES Frontispiece : In article number 2100171 by Matsuhiko Nishizawa and co‐workers, an array of porous microneedles (PMN) made of biodegradable poly(lactic‐co‐glycolic acid) (PLGA) is developed by a combination of molding and freeze‐drying methods. The reinforced PLGA‐PMN shows sufficient strength for insertion into a porcine skin and enables ionic connection and water permeation through its porous structure.
