A new strategy for synthesis of porous magnetic supraparticles with excellent biodegradability†
Abstract
Porous magnetic supraparticles (p-MSPs) with surface area up to 285.4 m2 gā1 have been fabricated by a one-step etching method, which is 4 times greater than the unetched counterpart. They exhibit significantly better biodegradability than their counterpart in both mimicked physiological buffer solution and the cellular environment of HeLa cells.
