Abstract
A multi-well assay plate is provided. The multi-well assay plate includes at least a top plate that defines a plurality of wells and a base plate having a substrate with well electrode structures patterned thereon. The well electrode structures are arranged in a plurality of sector electrical structures, each including a working electrode bus bar and a portion of an auxiliary electrode pattern. The substrate further includes at least one working electrode contact patterned on a bottom surface and an auxiliary electrode contact pattern disposed on the bottom surface.
Claims18
A multi-well assay plate comprising:
- a top plate having top plate openings defining wells of the multi-well assay plate arranged in a well pattern, each well being defined by a well area;
- a base plate including a substrate having a top surface and a bottom surface, the top surface being mated to the top plate;
- a plurality of sector electrode structures forming a plurality of well electrode structures, each of the plurality of sector electrode structures including at least one working electrode bus bar deposited on the top surface and a portion of an auxiliary electrode pattern deposited on the top surface;
- at least one working electrode contact patterned on the bottom surface in electrical communication with the at least one working electrode bus bar;
- and
- an auxiliary electrode contact pattern disposed on the bottom surface in electrical communication with the auxiliary electrode pattern, the auxiliary electrode contact pattern including a first plurality of cut-outs and a second plurality of cut-outs,
- wherein the first plurality of cut-outs are configured to accommodate the at least one working electrode contact and the second plurality of cut-outs are configured to create a plurality of isolation zones, and
- wherein each cut-out of the first plurality of cut-outs and the second plurality of cut-outs represents a gap in the auxiliary electrode contact pattern and is surrounded by the auxiliary electrode contact pattern.
A substrate having a top surface and a bottom surface, the substrate comprising:
- a plurality of electrochemical cells disposed on the top surface for performing electrochemical analysis, the plurality of electrochemical cells each including:
- one or more working electrode zones disposed on a surface of the cell, wherein each of the one or more working electrode zones are in electrical communication with one another,
- at least one auxiliary electrode disposed on the surface of the cell;
- and
- an auxiliary electrode contact pattern disposed on the bottom surface and in electrical communication with the at least one auxiliary electrode, the auxiliary electrode contact pattern including a first plurality of cut-outs and a second plurality of cut-outs, wherein the first plurality of cut-outs are configured to accommodate at least one working electrode contact in electrical communication with the one or more working electrode zones, and the second plurality of cut-outs are configured to create a plurality of isolation zones, and
- wherein each cut-out of the first plurality of cut-outs and the second plurality of cut-outs represents a gap in the auxiliary electrode contact pattern and is surrounded by the auxiliary electrode contact pattern.
