Improved stability and catalytic activity of graphene oxide/chitosan hybrid beads loaded with porcine liver esterase
{{output}}
Graphene oxide/chitosan and reduced graphene oxide/chitosan (GO/CS and RGO/CS) beads were prepared by precipitation with NaOH. Porcine liver esterase was immobilized on these beads to give GO/CS/E and RGO/CS/E beads. The optimum conditions for the maximum acti... ...
