Patent ID: 8920727

Claim:
A device for electrochemically measuring biochemical reactions, comprising: a base plate; a sensor array having at least two sensors formed on a first surface of the base plate, each sensor having an active surface for detection of the biochemical reactions; a coating on the first surface of the base plate, the active surfaces of the sensors being at least partially or fully free of the coating and regions of the base plate adjacent to the sensors being covered by the coating; and a sealing film having at least one recess through which, in mechanical combination with the base plate and/or the coating on the base plate, a flow cell is formed over the sensor array, the flow cell having at least one inlet/outlet channel formed as a continuous opening in the base plate, the at least one inlet/outlet channel corresponding to the at least one recess in the sealing film, wherein the active surfaces of the sensors and the coating on the base plate are spaced apart from one another so that trenches are formed around the sensors.
