实验测试结果表明:氧化铟锡（ITO）层厚度为23±5 nm时

在-1.4 V电位

制得折射率灵敏度为246 nm/RIU的LSPR芯片。

Abstract

A localized surface plasmon resonance（LSPR） biosensor devices which integrates in-situ chip preparation and online detection is designed

which reduces error caused by movement of chip in detection process and realizes device miniaturization

online detection

and simplification. Electrodeposition method is used to prepare Ag nanoparticle LSPR chips in this device

experimental results show that when the potential is -1. 4 V

the thickness of ITO layer is 23 ± 5 nm

the refractive index sensitivity of LSPR chips reaches 246 nm / RIU.
