Abstract
A sensor is provided. The sensor includes a field effect transistor comprising: an active region comprising a source region, a drain region, and a channel region between the source region and the drain region; a dielectric region on the channel region; an enzyme coupled to the dielectric region, the enzyme having an active site for interacting with a substrate; an electrolyte-screening layer coupled to the dielectric region, covering part of the enzyme while leaving the active site uncovered, thereby permitting interaction of the substrate with the active site, and a fluidic gate region to which the active site of the enzyme is exposed. A biosensing device including one or more of the sensors is also provided.
