The present disclosure is related to a bimetallic monatomic nano-enzyme electrochemical sensor, and a preparation method therefor and an application thereof. The bimetallic monatomic nano-enzyme electrochemical sensor comprises a working electrode, a counter electrode, a reference electrode and an electric signal control device; the working electrode is formed by coating a gallium-copper bimetallic monatomic nano-enzyme and a conductive carbon paste on a flexible carrier; and according to the present disclosure, the electrochemical sensor is constructed by loading a catalytic material of the gallium-copper bimetallic monatomic nano-enzyme on an electrode substrate material, which is used for detecting a volatile amine content in fresh meat, so as to detect a freshness of fresh meat.

Bimetallic monatomic nano-enzyme electrochemical sensor, and preparation method therefor and application thereof

An integrated rapid non-destructive detection system for multi-index of meat quality comprises a spectrometer for obtaining near-infrared spectra of a sample; an industrial tablet computer, comprising: a model embedding module for storing multiple prediction models; a model determining module connected with model embedding module and configured to call prediction model; an index prediction module connected with spectrometer and model determining module for receiving near-infrared spectra and predicting index data of the sample combining with called prediction model; wherein the number of detector elements of spectrometer is determined by an ultimate minimal resolution, and a resolution of the sample is controlled to the ultimate minimal resolution during an acquisition process; which realizes automatic black-white calibration, non-destructive detection of multi-index, improves building efficiency of model, while maintaining building stability, and optimizes detection instrument volume.
