Abstract:
1. An electrically controllable sensor arrangement comprising a plurality of arrays, each adapted for one of an electrochemical detection of molecular substances, transport and handling of charged molecules, wherein more than two sensor positions are provided on a substantially planar carrier ( a first guided wiring configured for electrically addressing the arrays ( wherein said first guided wiring allows for several sensor positions to be addressed by selecting at least one of row and column, for said addressed sensor positions to be read out substantially in parallel, but individually in an electric addressing procedure; a further guided wiring attributed to said carrier ( an electrical control arrangement having said second guided wiring, for electric control at said more than two arrays ( generating at least one of an electric direct field and alternating field at said arrays, detecting different electrochemical reactions or properties individually at said arrays, electrically reading out events having occurred at a sensor position between two electric addressing procedures of said same sensor position, transporting affinity-binding molecules onto one of said arrays, to a particular carrier being present there or into a gel being present there, independent of optical properties, and for immobilizing said molecules there.
