Field-Effect Transistors (FET) based biosensors provide easy signal read-out capabilities, lower detection limit, and higher sensitivity. The major drawback of these types of sensors it lacks because of its material degradation of the gate insulators and longer-term drift performance which possess instability in solution. ISFET’s based sensor has been processed for the very same as they deliver faster response, higher sensitivity, higher resolution, and label-free detection. Among various types of biological sensors, the semiconductor biosensors gathered attraction due to their superior advantage in the process of integration, multifunction, and miniaturization.
