摘要

Silver nanoparticles (AgNPs), owing to the property of plasmon resonance light scattering (PRLS), can be used as a light scattering spectral probe for visually tracing and detecting target molecules. In this study, we investigated the adsorption features of proteins immobilized on glass slides for AgNPs, and found that the scattering light of AgNPs adsorbed on the surface of glass slides could be seen by na-ked eyes under the irradiation of a common white light-emitting diode (LED) torch. Hereby, we estab-lished a method for visually determining the least complete quantity of immobilization of proteins on glass slides.
