Abstract: A laminate is provided that has an adhesive layer including a composition containing an acrylic block copolymer, the adhesive layer being so designed that it has a small change in adhesive force over time. The laminate includes an adhesive layer (B) including an acrylic adhesive composition (Z), and a substrate layer (A) including a polyolefin resin (a), the acrylic adhesive composition (Z) including an acrylic block copolymer (I) having one or more polymer blocks (b1) containing an acrylic acid ester-derived structural unit, and one or more polymer blocks (b2) containing a methacrylic acid ester-derived structural unit, the polymer block (b1) containing a structural unit derived from an acrylic acid ester (b1-1) represented by the general formula (1) CH2?CH—COOR1 (wherein R1 denotes a C7-C12 organic group).

Abstract: An electrochemical device for moving particles covered with a protein is provided. The device includes at least two electrodes that are in contact with a liquid containing the protein-covered particles and a circuit that generates a potential difference in a range that does not cause electrolysis of the liquid between the electrodes. The particles are moved by electrophoresis in the direction of the arrangement of the electrodes. The invention provided herein has numerous applications, including use in a microorganism concentration condensing device, a blood component induction device, and/or a blood component induction method, and/or an electric appliance that decreases the concentration of microorganisms present on the surface of a heat exchanger.
