The stages in the electrochemical detection of cancer cells. (I) Nanozyme functionalized with the EpCAM antibody (capture agent). (II) Dispersed the capture agent in cancer cells containing PBS buffer solution at pH 7.4. We extracted the cancer cells with an external magnet. (II) Biosensing platform developed. (IV) Transferred the cancer cells captured on the recognition platform. (V) Electrochemical detection and profiling of cancer cells using the amperometry method.
