Abstract:
1. A substrate for biomolecule microarray comprising one or more spots for immobilizing a biomolecule, in which said spot for immobilizing a biomolecule protrudes from the surface of the substrate and has a flat surface for spotting on the top thereof and comprises said flat surface for spotting surrounded by a lateral surface that is inclined to said flat surface for spotting at an angle ⊖, which spot is hereinafter referred to as a “protruding spot part”; and at least the surface of the substrate around the protruding spot part and the protruding spot part, including the flat surface for spotting and the lateral surface, are comprised of an electrically conductive substance, wherein said surface of the substrate around the protruding spot part forms a roughly V-shaped bottom surface and wherein the intensity of light detected from said V-shaped bottom surface when read by a confocal detector is different from the intensity of light detected from said flat surface.
