Transistor-based molecular detection apparatus and method

Abstract From the Canadian patent

Adjacent first and second transistors are integrated with a substrate. Each of the, first and second transistors has a gate electrode a source electrode, a drain , electrode and a semiconductive channel formed of an organic material the semiconductive , channel, electrically coupling the source electrode with the drain electrode. The source electrode, of the first transistor is electrically coupled to the source electrode of the second, transistor. A molecular receptor is bound directly to a surface of the semiconductive, channel of the first transistor. A non-zero offset voltage which produces , equal channel, currents in the semiconductive channels of the first and second transistors …
