摘要

In this work, gold nanoparticles (AuNPs) binding dynamics have been studied on the amine-functionalized surface by the attenuated total reflectance (ATR) based evanescent wave absorption method. During binding, the real-time absorption peak of localized surface plasmon resonance (LSPR) was monitored. The immobilization time has been found to be decreased with the higher molar concentration of AuNP...
