长程表面等离子体共振生物传感器的制备与应用
Preparation and Applications of Long-range Surface Plasmon Resonance Biosensors
摘要
Abstract
Long-range surface plasmon resonance(LRSPR)is a novel surface optical phenomenon by coupling the evanes-cent fields on the opposite interfaces of an ultrathin metallic film embedded between two dielectric layers with same/similar refractive indices.In contrast to conventional surface plasmon resonance(cSPR),LRSPR exhibits a stronger surface elec-tromagnetic field,a longer propagation length,as well as a larger penetration depth.Consequently,LRSPR-based biosensors are believed to be particularly suitable for the detection of large biomolecules(e.g.,cells,bacteria,etc)and the real-time monitoring of cellular behavior.In order to better understand the state of the art in LRSPR biosensors,we herein summarize the physical principles behind the LRSPR,the fabrication of LRSPR chips and their biosensing applications.关键词
