23 Jul Preparation method of nano meso-porous silicon composite hydrogel with controlled release function
Abstract
The invention discloses a preparation method of nano meso-porous silicon composite hydrogel with a controlled release function. The preparation method includes the steps that micromolecular medicine is loaded in meso-porous silicon nano-particles; an oxidized hyaluronic acid and carboxymethyl chitosan solution is prepared, and the medicine-carrying nano-particles are added into the hyaluronic acid solution to be ultrasonically treated and then stirred to be uniform; a medicine-carrying nano composite hydrogel carrier is prepared. The prepared nano composite hydrogel has good mechanical performance, biocompatibility, biodegradability and medicine slow release effects, and has potential of being applied to the fields of tissue engineering and biological medicine treatment. In addition, the preparation method of the nano composite hydrogel is simple, cost is low, and large-scale production can be achieved.
