Abstract: Devices for detecting an analyte in a sample suspected of containing the analyte, are provided. The devices include bio-functional, nanostructured, isoporous membranes (BNIM) integrated organic electrochemical transistor (OECT), herein BNIM-OECT, for the rapid and sensitive detection of the presence of an analyte of interest, in a sample, for example, a biological sample. The membrane (i.e., BNIM) is physically separated from the OECT channel therefore the electronic device can be used multiple times. The isoporous membrane is functionalized to include a binding partner for the analyte being detected. The BNIM-OECT can be used for disease detection, by functionalizing the BNIM-OECT with a binding partner to an analyte associated with the disease, applying a collected biological sample to the BNIM-OECT. A decrease in channel current as a result of analyte binding to its binding partner on the isoporous membrane indicates the presence of the analyte in the sample.
