Abstract

Official abstract text for this publication.

Provided herein is a hydrogel composition comprising a graphene, a chitosan, and a polyethylene (glycol) diacrylate (PEGDA) (PCG hydrogel). In some embodiments, the hydrogel further comprises a N-isopropylacrylamide (NIPAM) (TPCG hydrogel). Also provided is a method for differentiating a mesenchymal stem cell comprising contacting the cell with the PCG hydrogel. Further provided herein is a method for delivering a pharmaceutical composition to a cell comprising administering to the cell a TPCG hydrogel and the pharmaceutical composition.

First claim

Opening claim text (preview).

The invention claimed is: 1. A hydrogel composition comprising: at least two acrylated chitosan-graphene monomers, where each chitosan-graphene monomer comprises: carboxylic acid functionalized graphene, where the chitosan component of the chitosan graphene-monomer is covalently bonded to the carboxylic acid functionalized graphene component of the chitosan-graphene monomer; and polyethylene (glycol) diacrylate (PEGDA), where the PEGDA covalently crosslinks the at least two ac…
