Abstract

The invention discloses a local electrochemical imaging test system based on surface plasma resonance. The local electrochemical imaging test system comprises an optical system, a mechanical system, a data acquiring system, a circulation system, an electrochemical system and a computer control system, wherein the optical system comprises an SPR (surface plasma resonance) chip, an optical prism and a light source; the light source emits an incident laser and irradiates to the optical prism; the circulation system comprises a micro-fluidic test tank, wherein a to-be-tested article flows through the upper surface of the SPR chip via the micro-fluidic test tank to cause the change of a surface plasma resonance absorption peak; the electrochemical system provides electrical stimulation to the to-be-tested article to carry out the electrochemical reaction on the to-be-tested article and acquires corresponding electrochemical signals; the data acquiring system acquires the change of the surface plasma resonance absorption peak; the mechanical system is used for adjusting the angle of the incident laser emitted from the light source; and the computer system obtains corresponding information of the to-be-tested article according to the electrochemical signal and the change of the surface plasma resonance absorption peak.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a local electrochemical imaging test system based on surface plasmon resonance. Background technique [0002] Electrochemical detection is a very effective analytical method and has a wide range of applications in many fields. However, the conventional electrochemical detection method is to detect the current or other electrical quantities of the entire electrode, which cannot directly obtain the local reaction information on the electrode surface, nor can it obtain its imaging information, and lacks spatial resolution. Local electrochemical detection technology emerged as the times require. It is a new technology for in-situ electrochemical performance testing with spatial resolution. It can indicate the position and activity of electrochemical active points in the two-dimensional micro-area on the electrode surface, and track the changes of active points. process. In the pr...
