Abstract
In this paper, uniform and porous gelatin microgels with various functional nano-objects (platinum nanoparticles and magnetic nanoparticles) were prepared by a ‘casting’ strategy in a controllable manner. During the microgels fabrication, two kinds of nanoparticles can be simultaneously introduced into the microgels without mutual influence, endowing the microgels with the combined functionality of nano-objects. Experimental data showed that the microgels with various nano-objects are stable enough in strong base or acidic solution, and can be taken as an efficient catalysis system and conveniently separated from the reaction medium by magnetic field. The method proposed here is certified to be facile, efficient and low cost to fabricate stable multifunctional microgels.
