Description
Summary:	We present a modular platform for mobile biosensing using an extended gate field-effect transistor architecture. Our device contains transduction hardware for amplifying changes in electrochemical cell potential in an analyte-agnostic manner and can be interfaced with a wide variety of functionalized electrodes for the detection of any analyte for which a suitable recognition element exists. Here, the device is presented and characterized, and its applicability demonstrated using a panel of example electrode systems for the measurement of picomolar concentrations of neuropeptide Y and insulin, as well as variations in pH.
