Abstract :
This paper describes the development of a sensor for the detection of viruses. The detection scheme uses sense and dummy capacitors and a sense amplifier circuit to compare capacitance values. The presence of sufficient biological material within the sense capacitor alters the sense amplifier output. This promising approach has the potential to more rapidly test for the presence of virus using an IC platform.
