Abstract:
1. An apparatus for analysis of a plurality of biochips, each biochip comprising an array of electrodes comprising capture binding ligands and an auxiliary electrode, the apparatus comprising: a) a plurality of sets of stations wherein each set comprises: i) a plurality of stations, each configured to receive at least one of said plurality of biochips, wherein each station comprises a plurality of array interconnects for electrical communication with said array of electrodes of a first biochip of said plurality of biochips and at least one auxiliary interconnect positioned for electrical communication with an auxiliary electrode of said first biochip; ii a thermocontroller, configured to independently thermally control one of said plurality of said sets; b) a signal generator coupled to said plurality of array interconnects and said auxiliary interconnect and configured to apply an input signal to said electrodes of said array of electrodes of said first biochip during an electrochemical measurement; and c) a detector coupled to said plurality of array interconnects and configured to receive an output signal from said electrodes of said array of electrodes of said first biochip during said electrochemical measurement.
