Patent ID: 7182853

Claim:
A method of performing an analysis of a sample comprising: providing a sample in a test region; providing a target in the test region; providing an electrochemical control for the redox environment of the sample; wherein the electrochemical control is provided to control each of a multiplicity of test regions, and wherein the test regions are each of a multiplicity of wells in a microplate, and wherein the electrochemical control may be operated to separately control the redox environment of each well in a microplate, and wherein the electrochemical control has at least two electrodes contained on a plate with protrusions wherein the electrodes are deposited on the protrusions of the plate and the plate is placed over the microplate so that the protrusions of the plate fit into the wells of the microplate, and wherein the protrusions are cone shaped; operating the electrochemical control to control the redox environment of the sample; and analyzing the sample using a detection scheme, wherein the detection scheme is operated to identify if interaction has occurred between the target and the sample, whereby activity of the sample under redox conditions can be identified.
