主 题:surface plasmon resonance(SPR) detection range linearity sensitivity resolution
摘 要:In recent life science research,identifying and characterizing entire biomolecular interaction networks is prerequisite to understanding cellular processes on a molecular and biophysical level.A surface plasmon resonance (SPR) imaging interferometer based on spatial phase modulation detection is presented to meet this *** this method,the SPR sensing chip surface is illuminated with collimated parallel light beam,and a Wollaston prism is introduced into the reflected light path to produce the interference of polarized light reflected from SPR sensing *** of biomolecular interactions can be obtained by extracting the phase change from the SPR interference *** our interferometer,we made experiments on a series concentration of NaCl solutions to investigate its detection range,linearity,sensitivity and *** results indicate that the SPR imaging interferometer is mainly sufficient for biomolecular interaction detection.
