Electrolyte‐gated nanoscale silicon field‐effect transistor sensors provide exceptional charge sensitivity and direct electrical readout. However, their sensing accuracy is fundamentally limited by low‐frequency noise and baseline drift. This review examines the origins of noise and drift in these sensors, summarizes the key mitigation strategies, and ...
