Description

technical field [0001] The invention provides an electrochemical in-situ time-resolved surface plasmon resonance measuring instrument. Background technique [0002] The surface plasmon resonance method has the characteristics of real-time detection, no need for labeling, and less sample consumption. It can monitor the progress of the binding or dissociation reaction between molecules on the sensor surface in real time, and then obtain information about molecular structure changes and chemical bonding, and calculate the reaction rate. Kinetic constants determine the type, concentration and quality of reactants, and all these experiments do not require labeling and purification of reactants, so it is especially suitable for the study of interactions between biomolecules. Electrochemical method, as a simple, rapid, accurate, and high-sensitivity analysis, detection and characterization method, has always occupied a more important position in scientific research and production. ...

Problems solved by technology

However, the simple combination of the two also has obvious shortcomings: the time-resolved measurement of the plasmon resonance absorption on the surface of the ultra-thin film cannot be measured at the same time as the electrochemical on-site measurement; the conditions of the two groups of tests cannot be guaranteed to be completely consistent ( Such as changing the chip, solution, etc.); the simultaneous measurement of the electrochemical response system is powerless; the time resolution is not high; the integration of the instrument is poor; the experimental operation is cumbersome; the data communication rate is low
