Abstract
A biosensor has one or more field effect transistors each comprising a source region and a drain region separated by a channel region and a gate positioned offset and spaced from the channel region. The biosensor also has one or more molecular probes coupled to at least one of the channel region and the offset gate, the one or more molecular probes configured to mate with at least one target. A method for detection of a target is also disclosed. One or more targets are immobilized as an electric field shunt between an offset gate and a channel region for one or more biosensors. A target measurement value is determined in proportion to a number of the one or more biosensors having the electric field shunt.
