Abstract

The invention discloses a detection device and method for biological regulation of localized surface plasmon resonance. The device includes a test bench, the test bench includes an incident optical fiber interface for accessing a light source and an outgoing optical fiber interface connected with a spectrophotometer, a cuvette is arranged between the incident optical fiber interface and the outgoing optical fiber interface, and the The detection electrode chip is inserted in the cuvette. The method utilizes the detection device to detect the localized surface plasmon resonance of biological regulation. The invention realizes the localized surface plasmon resonance of the bioreaction regulation by placing the bioregulation chip in the cuvette, and has the advantage of realizing biosensing.

Description

technical field [0001] Embodiments of the present invention relate to an optical detection technology of localized surface plasmon resonance, and in particular to a detection device and method for biological regulation of localized surface plasmon resonance. Background technique [0002] Local surface plasmon resonance (LSPR) is a resonant absorption phenomenon of photon energy that occurs on nanoparticles. The influence of surface modification, etc., is often used in the field of sensing. As a typical nanomaterial, gold nanoparticles are widely used in the field of biomedicine because of their simple preparation process and good biocompatibility. Gold nanoparticles play an important role in the construction of electrochemical and optical sensors due to their high specific surface area characteristics, good size control characteristics, and excellent ultraviolet-visible spectral absorption characteristics. [0003] The distribution of free electrons on the surface of gold ...
