This work reports a novel, ultrasensitive, and selective sensing platform based on a direct electrodeposition of electrochemical reduced graphene oxide (ERGO)-Au nanoparticles (AuNPs)-β-cyclodextrin (β-CD) and Prussian blue-chitosan (PB-CS) on glass carbon electrode (GCE) for efficiently fixed acetylcholinesterase (AChE) to fabricate organophosphorus(More)
A novel β-glucan biosensor was fabricated by immobilizing β-glucanase (β-G) with glucose oxidase (GOD) on nano-Prussian blue-chitosan (PB-CS) and gold nanoparticles-chitosan (AuNPs-CS) composites. Both the PB-CS and AuNPs_CS film were directly electrodeposited on the surface of gold electrode. The morphology of the AuNPs-CS/PB-CS nanocomposites was(More)
A stable and controllable Prussian blue (PB) layer electrodeposited on self-assembled monolayers (SAMs) of thioctic acid amide (T-NH(2)) on gold electrode was prepared. The PB, combining with biocompatible matrix chitosan, was used for the highly efficient immobilization of glucose oxidase (GOD) for sensitive biosensing of glucose. The PB on SAMs exhibits a(More)
A simple, ultrasensitive peroxynitrite anion (ONOO-) electrochemical sensing platform was developed by immobilizing hemin on a density controllable electrochemically reduced graphene oxide-Au nanoparticles (ERGO-AuNPs) nanohybrids. The ERGO-AuNPs in situ nanohybrids were produced onto a glass carbon electrode (GCE) by one-step electrodeposition, the density(More)
