Abstract
A biosensor array having a substrate, a plurality of biosensor zones arranged on the substrate, each of which has a first terminal and a second terminal, at least one drive line and at least one detection line, the at least one drive line being electrically insulated from the at least one detection line. In each case the first terminal of each biosensor zone is coupled to precisely one of the at least one drive line and the second terminal of each biosensor zone is coupled to precisely one of the at least one detection line, and at least one of the at least one drive line and at least one of the at least one detection line is coupled to at least two of the biosensor zones. The biosensor array also has a drive unit for providing an electrical drive signal, a detection unit for detecting an electrical detection signal resulting from the electrical drive signal, and a selection unit that couples the drive unit to the drive line of a biosensor zone to be selected and the detection unit to the detection line of the biosensor zone to be selected, whereby the biosensor zone is selected.
