Phys.org  May 18, 2021 An international team of researchers (USA – University of Florida, Taiwan) has developed a sensor system which amplifies the binding signal for a target biomarker using a disposable and biofunctionalized strips, which can be connected externally to a reusable printed circuit board for signal amplification with an embedded MOSFET. The sensor was externally connected to the gate electrode of the MOSFET, and synchronous pulses were applied to both the sensing strip and the drain contact of the MOSFET. The resulting changes in the dynamics of drain waveforms were converted into analog voltages and digital readouts, which […]
