Polydopamine functionalized reduced graphene oxide-silver nanoparticle (PDA-RGO/Ag NP) nanocomposites were successfully prepared by a simple and mild procedure. Graphene oxide (GO) sheets were firstly coated with PDA via a self-polymerization process which provided an excellent interface for in-situ growing silver nanoparticles. Fourier transform infrared spectroscopy (FTIR) confirmed the successful...
A silver nanocomposite was one‐step synthesized in chitosan solution and used to prepare an immunosensor with the aid of gold nanoparticles (Au NPs) assembly. The Ag NPs at the immunosensor exhibited sensitive electrochemical stripping signal in KCl solution. After a sandwich immunoreaction, the current response of the immunosensor decreased due to the formation of antibody‐antigen immunocomplex on...
