A combinatorial chemistry formation and assay disc (1) having a base (20), an upper surface (26) and a lower surface, and a data surface (40), one of the upper or lower surfaces being an assay surface The data surface is spaced from the assay surface and is formed by combinatorial chemistry and assay disk (1) on or within the assay disk. The assay surface comprises a conductor layer (64) on the base, a dielectric or photoconductor layer (66) on the conductor layer, and a chemical functional layer (66) on the dielectric or photoconductor layer. 68, 69). The assay surface may be flat or may include a three-dimensional structure (100, 168). |
