Abstract

The invention discloses a multi-channel surface plasma wave sensing-monitoring system, which comprises a SPR biological sensing-monitoring device, an incident light channel, an exit light channel and an intelligent analysis processing platform, wherein the SPR biological sensing-monitoring device comprises a SPR biological sensor and an adjustable detecting light source, the incident light channel comprises a cruising adjustable polarized light source which comprises a polarized light source and a control system, and the exit light channel comprises a convergent lens and a photodetector. The multi-channel surface plasma wave sensing-monitoring system can accurately analyze the interaction (the function of multiple factors) of various matters in specimens, avoids system deviation which is brought by single measurement, greatly reduces monitoring time, and improves monitoring efficiency. The invention has the advantages of compact structure, convenient carrying, convenient employment and high sensitiveness, which can be applied in a plurality of fields and various environments, and has wide application prospect.

Description

technical field [0001] The invention relates to the field of biosensors, in particular to a multi-channel surface plasmon wave sensing and detection system. Background technique [0002] Surface plasmon resonance (SPR) is a physical optics phenomenon. Surface plasmon resonance detection is a detection technology using surface plasmon waves (SPW, Surface Plasma Wave), which has the advantages of no labeling, high speed, specificity, high sensitivity, and a large number of parallel screening. Surface plasmons (SP) are formed by electromagnetic waves propagating along the interface between a metal and a dielectric. When the polarized light parallel to the surface is incident on the interface at an angle called surface plasmon resonance, when attenuated total reflection occurs, the incident light is coupled into the surface plasmon, and a large amount of light energy is absorbed. At this angle, due to the surface plasmon resonance Causes a significant reduction in reflected li...
