摘要
金属纳米颗粒表现出来的局域表面等离子体共振效应被广泛应用于生物传感器领域。综述了局域表面等离子体共振效应的基本原理,对比了局域表面等离子体和表面等离子体的异同,详细介绍了胶体化学平板印刷术、电子束光刻法、聚焦离子束光刻法、纳米球光刻术等多种金属纳米颗粒阵列和图形制备技术、特点及应用,分析了局域表面等离子体共振生物传感器的应用前景、现存问题及其解决途径。
Metal nanoparticles exhibit the localized surface plasmon resonance（LSPR） effects, and have been widely applied in biosensor. In view of the main principle of localized surface plasmon effects, and analysing the differences between surface plasmon and localized surface plasmon are reviewed. Fabrication technology, characteristics and application of several metal nanostructure fabrications in LSPR biosensors are listed, such as colloidal lithography, electron beam lithography, focused ion beam, nanosphere lithography. The prospective, challenges and solutions that LSPR biosensors should be faced are also discussed.
