Description

technical field

[0001] The invention belongs to the field of electrochemical detection, and in particular relates to a multi-microelectrode integrated sensor chip and its application in biochemical enzyme-free rapid detection. Background technique

[0002] The real-time detection of POCT has the characteristics of fast, convenient, and cost-saving. The specific performance is that the detection results can be obtained immediately, the cost of single-body inspection is reduced, and the requirement of obtaining accurate inspection results in the shortest time is met. widely used.

[0003] At present, the latest POCT chemical sensing instrument products can realize the detection of multiple samples at the same time, which greatly saves the detection time and makes the instant detection faster. POCT devices are mostly realized by biosensors. By immobilizing biological enzyme molecules on the solid phase interface of microanalytical devices, the analytes are specifically identif...
