▎ 摘　　要

NOVELTY - Hydrogel composition comprises graphene, chitosan, and polyethylene(glycol)diacrylate (PEGDA). USE - The hydrogel composition is useful in products including disposable diapers, contact lenses, electrodes, and water gel explosives, and as scaffolds in tissue engineering. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method of differentiating mesenchymal stem cells, involves contacting the cells with the hydrogel composition; and (2) method of delivering a pharmaceutical composition to a cell, involves administering to the cell a hydrogel composition comprising graphene, chitosan, PEGDA, and N-isopropylacrylamide (NIPAM), and increasing the temperature of the hydrogel to 36-42 degrees C.
