The biosensor array comprises a row biosensor, a line biosensor, a row decoder circuit, a line decoder circuit and a control logic circuit, wherein the row biosensor is connected with the row decoder circuit, the line biosensor is connected with the line decoder circuit, and the control logic circuit is coupled to the row decoder circuit and the line decoder circuit. The biosensor array based on the ion sensitive field effective transistor, provided by the invention, has the beneficial effects that the detection area is greatly covered, a plurality of targets are simultaneously detected rapidly in real time through measuring a large quantity of sensors inside the biosensor array, the statistical error of the detection is greatly reduced, and thus the accuracy and the repeatability of the detection are improved.

Description

technical field [0001] The invention belongs to the field of biosensors, in particular to a biosensor array based on ion-sensitive field effect transistors. Background technique [0002] Since the biosensor was proposed by Clark and Lyons in 1962, it has been deeply valued and widely used in fermentation technology, environmental monitoring, food engineering, clinical medicine, military and military medicine. The initial biosensors were mainly based on the development of biosensors made of enzyme electrodes. However, due to the high price and poor stability of enzyme preparations, the application of enzyme biosensors is limited to a certain extent. In recent years, with the continuous development of molecular biology and microbial immobilization technology, DNA sensors and microbial cell sensors have gradually become the mainstream of biosensor development. Microbial sensors can truly evaluate the biological effects of target substances in the environment. Relevant research...
