▎ 摘　　要

Hydrogels have been applied to various fields due to their excellent biocompatibility and flexibility like human tissue. In particular, hydrogels that respond to stimuli have attracted attention from biosensor materials. In this study, graphene oxide (GO) was introduced into poly(2-acrylamido-2-methyl-1-propanesulfonic acid) (PAMPSA) to manufacture a composite hydrogel sensitive to specific pH, and the applicability of the prepared hydrogel as a pH-responsive sensor was examined.
