Abstract
The present invention provides a tissue identification method and a biosensor for tissue identification. The tissue identification method comprises a preparation step and a detection step, wherein the preparation step comprises preparing a biosensor, the biosensor comprises a transistor and a reaction electrode, the reaction electrode is spaced from the transistor relative to the grid terminal of the transistor, and the detection step comprises: placing a biological tissue sample to be identified on the reaction electrode, applying a pulse wave voltage having an adjustable pulse wave width and an adjustable pulse wave height on the reaction electrode to produce pressure difference between the reaction electrode and the grid terminal of the transistor, and measuring and calculating the detection current generated by the transistor in the pulse wave width so as to obtain a first sensing index. The present invention further provides a biosensor for tissue identification. With the tissue identification method and the biosensor of the present invention, the tissue can be effectively, simply and rapidly identified so as to effectively and safely perform surgical medical surgeries.
