Fabrication of Au Nanoparticles Film Sensor Based on Localized Surface Plasmon Resonance

摘要

Layer-by-layer assembly technique is a simple, economic, and rapid rmethod that can be applied in textile field, especially in producing high-tech fabrics with superb performance.Here, we use this method to produce the Au nanoparticles(Au NPs) film on quartz palate.Because of the localized surface plasmon resonance(LSPR), the Au film can be sensitive to the refractive index and have a resonance peak shift in ultraviolet zone.Compared different size of the Au NPs, the larger size nanoparticles are more sensitive to the refractive index.This kind of the Au NPs film has a potential application in bio-sensor.
