Abstract
Systems and methods for sensing analytes using an extended gate field effect transistor (EGFET) are provided. A biosensing system can utilize a biodetection layer on a substrate, which can be coupled to a field effect transistor (FET). The coupling can be such that the gate of the field effect transistor is connected to the substrate having the biodetection layer thereon. The functionalized substrate can include a well-defined area that can hold a specific, pre-determined volume of fluid on top of it. An external electrode can be dipped in the fluid and can then be connected to a power source supplying a gate voltage. The presence or concentration of the target analyte in the fluid can be determined based on the source-drain characteristics of the FET.
