Abstract

Claims (12)

1 . An AECL tag composition, comprising:

2 . The AECL tag composition of claim 1 , wherein M n+ is Ru 2+ .

3 . An assay plate for mounting a solid state microarray,

said assay plate comprising: a pillar, said pillar comprising a top surface and a bottom surface, said top surface comprising a mounting surface to receive a solid state microarray and at least one working electrode and one counter electrode configured to contact and to be in electrical communication with a corresponding at least one working electrode and counter electrode on a bottom surface of said solid state microarray, said bottom surface of said pillar comprising contacts for supplying power to said at least one pillar working electrode and counter electrode,

wherein said solid state microarray comprises an addressable network of working electrodes and counter electrodes integral to said microarray, wherein said working electrodes comprise chemically-functionalized surfaces comprising functional groups, said functional groups capable of covalently binding capture ligands at defined locations on a substrate, and said capture ligands capable of specifically binding said target biomolecules thereby immobilizing said target biomolecules at said defined locations on said substrate.

4 . The assay plate of claim 3 , comprising a plurality of pillars.

5 . The assay plate of claim 4 , wherein said plurality is 24, 96, 384 or 1586.

6 . The assay plate of claim 3 , wherein said pillar comprises at least 2, 4, 8, 16, 32, 64, 100, 200, 500, 1000, 2000, 5000, 10,000, 15,000, 20,000, 30,000, 40,000, 50,000, 60,000, 70,000, 80,000, 90,000, 1,000,000, 1,500,000, 2,000,000 or more working electrodes.

7 . An assembly, comprising a solid state microarray that comprises: an addressable network of working electrodes and counter electrodes integral to said microarray, said working electrodes comprise chemically-functionalized surfaces comprising functional groups, wherein said solid state microarray is mounted on said pillar mounting surface of said assay plates of claim 3 , and wherein said working electrodes and said counter electrodes of said solid state microarrays are in electrical communication with said working electrodes and said counter electrodes of said pillars.

8 . The assembly of claim 7 , wherein at least 50, 100, 200, or 500 separate analytes can be detected on one or more solid state microarrays mounted onto a single pillar.

9 . The assay plate or assembly of claim 8 , further comprising an assay cap configured to engage with said assay plate and comprising pillar struts mounted to pillar walls, wherein said pillar struts are configured to slide into corresponding grooves on the sides of said assay plate pillars and thereby position said pillar walls on top of said pillars.

10 . The assay plate or assembly of claim 9 , wherein said pillar walls comprise a reservoir for containing an assay solution in contact with said solid state microarray.
