Abstract:

As the intermediate product of protein hydrolysis, peptides are synthesized through the polymerization of α-amino acids. Given the great biocompatibility and surface plasmon resonance(SPR) of gold nanoparticles(AuNPs), biosensors based on the peptide-AuNPs system have attracted the attention of many scientists. In this review, the biosensing research and application of the peptide-AuNPs complexes are summarized, including the preparation and properties of peptides and AuNPs, the synthesis of peptide-AuNPs and the application in biosensing.

Key words: peptide, the modification of gold nanoparticles, biosensing
