This paper presents a new electronic methodology to detect DNA hybridization for rapid identification of diseases, as well as food and environmental monitoring on a genetic base. The proposed solution exploits a new (electrical) capacitive measurement circ ...
In this work we present the first results on a 'label-free' DNA analysis system based on hydrogenated amorphous silicon (a-Si:H) thin film sensors. The detection mechanism is based on absorbance measurements performed on DNA molecules in a buffer solution. ...
Reliable split C(V) measurements are shown to be feasible on ultra-thin oxides (down to 1.2 nm) by using relatively small area MOSFETs (typically 100 mum(2)). To this end, specific correction procedures for parasitic parallel capacitances and gate leakage ...
