Abstract
Graphene sheets functionalized covalently with biocompatible poly-L-lysine (PLL) were first synthesized in all alkaline solution. PLL-functionalized graphene is water-soluble and biocompatible, which makes it a novel material promising for biological applications. Graphene sheets played an important role as connectors to assemble these active amino groups Of Poly-L-lysine, which provided a very biocompatible. environment for further functionalization, such as attaching bioactive molecules. As an example, an amplified biosensor toward H2O2 based on linking peroxidase onto PLL-functionalized graphene was investigated.This publication has 33 references indexed in Scilit:
