Abstract

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.


수화젤은 인체 조직처럼 생체 적합성과 유연성이 뛰어나 다양한 분야에 활용되어 왔다. 특히 자극에 반응하는 수화젤은 바이오센서의 소재로 많은 주목을 받고 있다. 본 연구에서는 poly(2-acrylamido-2-methyl-1-propanesulfonic acid)(PAMPSA)에 graphene oxide(GO)를 도입하여 특정 pH에서 감응하는 복합체 수화젤을 제작하였으며, 제작된 수화젤의 pH 감응 센서로서 응용 가능성을 살펴보였다.


Keywords: poly(2-acrylamido-2-methyl-1-propanesulfonic acid), graphene oxide, pH-responsive hydrogel sensor.
