Description

technical field [0001] The invention relates to the field of biological detection, in particular to an electrochemical detection composition for alanine aminotransferase, its application, an electrochemical sensor and a detection method. Background technique [0002] Alanine aminotransferase is an important enzyme in human metabolism. Quantitative detection of the concentration of alanine aminotransferase in the human body can understand the current degree of liver function damage in the human body and judge the effect of treatment, and can also perform routine liver function testing on healthy people. [0003] Generally, the concentration of alanine aminotransferase in the human body is characterized by the detection of alanine aminotransferase in blood. Electrochemical sensors are one method used to detect the concentration of components in blood. The use of electrochemical sensors to detect the concentration of components can be tested by collecting fingertip blood. The...
