A H2O2-free electrochemical peptide biosensor based on Au@Pt bimetallic nanorods for highly sensitive sensing of matrix metalloproteinase 2†
Abstract
Inspired by the excellent catalytic activity of Au@Pt bimetallic nanorods, we construct a H2O2-free electrochemical peptide biosensor based on Au@Pt bimetallic nanorods for highly efficient and sensitive sensing of MMP-2 for the first time, not only simplifying the traditional testing steps but also avoiding the potential damage caused by H2O2 to peptides and proteins.
