| 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. |
