Abstract: A substrate for a biomolecule microarray having one or more spots for biomolecule immobilization. Each spot projects from the surface of the substrate and has a flat surface for a spot at the top, and at least the areas of the substrate around the projecting spots, a projecting spot side surface, and the flat surface are made of a conductive material. Alternatively, each spot projects from the surface of the substrate and has a flat surface for a spot at the top, adjacent projecting spots are jointed with their projecting spot side surfaces, and at least projecting spot side surface and the flat surface are made of a conductive material. A biomolecule interaction acceleration device is also disclosed which has an electrode so disposed as to face the surface of the microarray on which a biomolecule immobilization spot is provided and a power supply for applying an electric field between the microarray and the electrode.
