摘要

研制了一种利用金纳米粒子(Au NPs)的局部表面等离子体共振(LSPR)的多功能光学传感器。将15 ~ 30 nm的金薄膜溅射在玻璃衬底上，通过热退火法制备了不同尺寸和分布的金纳米颗粒。建立了由微流控电池和光学分光光度计组成的测量装置，用于测量金纳米颗粒在不同介质中的表面等离子体共振光谱。研究了纳米颗粒作为传感器(如气体传感器、化学传感器、生物传感器)的可能应用。

Development of a localised surface plasmon resonance sensor based on gold nanoparticles

A versatile optical sensor which utilizes localized surface plasmon resonance (LSPR) on gold nanoparticles (Au NPs) was developed and investigated. Gold nanoparticles in various size and distribution were generated by thermally annealing gold thin films (15-30 nm) which were sputtered on glass substrate. A measurement setup consisting of a microfluidic cell and an optical spectrophotometer was constructed to measure the surface plasmon resonance spectra of the gold nanoparticles in different media. The possible application of the nanoparticles as sensors (e.g. gas sensor, chemical sensor, biosensor) was investigated.
