  • Publication number: 20100029503
    Abstract: This invention is directed to an analysis chip comprising a substrate having a surface on which a selective binding substance is immobilized; a cover member adhered to the substrate; and particles movably contained or injected in a void between the substrate and the cover member; wherein the surfaces of the particles are coated with a surfactant. By this invention, generation of bubbles which inhibit the selective reaction between the test substance and the immobilized selective binding substance is suppressed, thereby reducing the deviation of data, suppressing the lowering of sensitivity, and promoting the reproducibility of the measurement.
