This ISSSR 2010 paper by Handel, Henning, Truong, and Nasiri Avanaki examines quantum 1/f noise in FET-based biochemical sensors. The research analyzes fundamental noise limitations in field-effect transistor biosensors, investigating how quantum 1/f noise, thermal noise, and shot noise establish detection limits for biomolecular sensing, providing theoretical framework and design strategies for optimizing sensitivity in electronic biosensors for protein detection, DNA sequencing, and real-time molecular diagnostics applications.
