Abstract

In this study, gold nanoparticles (AuNPs) were used as carriers of the signaling anti-chicken antibody peroxidase in comparison with anti-chicken antibody peroxidase without gold nanoparticle in a commercial avian influenza kit. AuNPs enhanced the absorbance and shortened the assay time. AuNPs act as a carrier of many enzymes and multiply the effect of enzyme when reacting with substrate. They amplify optical signal, while keeping low background signals.
