By analyzing and fitting current change curves and transfer characteristic curves under two drugs, camptothecin and doxorubicin, this technique quantifies both the magnitude of drug-induced current changes in cells and the rate of drug entry into cells. Flow cytometry was utilized to validate the entry rates of two drugs, camptothecin and doxorubicin, into the cells. The biosensor leverages the exceptional sensitivity of two-dimensional electron gas to detect proximal charge variations at ultralow concentrations, even in fluids with high ionic strength. The findings reveal that anti-cancer drugs have a more pronounced impact on tumor cells, with the effects and interaction speeds differing across normal cells and tumor cells. This innovative approach not only enhances our understanding of the specificity and action mechanisms of anti-cancer drugs but also provides a valuable tool for screening potential tumor anti-cancer drugs and advancing targeted cancer therapies.  \nKeywords: field-effect transistor biosensors; rapid detection; anti-cancer drugs; camptothecin; doxorubicin; drug action speed  \n1. Introduction  \nMalignant tumors pose a significant threat to human health, with drug therapy being one of the most common and essential treatment approaches [1,2] . Recently, precision medicine has emerged as a leading trend in cancer treatment [3–5] . To achieve effective and targeted drug therapy for malignant tumors, drug screening plays a crucial role [6] . Anti-cancer drugs exert cytotoxic effects on neoplastic cells, but the impact of different drugs on the same cell type can vary significantly; also, the strong killing effect of antitumor drugs on normal tissues may limit their suitability for tumor treatment [7,8] .
