Abstract: An electrically conductive material including a base and a conductive polymer applied uniformly to the base's surface and having a reduced resistance value. Specifically, the electrically conductive material includes PEDOT-pTS, serving as a conductive polymer, applied to the base comprised mostly of silk. Also the enclosed provide a method for producing the electrically conductive material, and a bioelectrode including it.

Abstract: A proteoliposome, which is obtained by removing a surfactant from a mixed solution including lipid, membrane proteins and the surfactant, wherein the content of the surfactant in the mixed solution is equal to or more than 1.5 times of the sum of a maximum amount of the surfactant associating with the lipid and a maximum amount of the surfactant associating with the membrane protein. A biochip wherein the above-described proteoliposome is spread on a substrate. A method for producing a proteoliposome by removing a surfactant from a mixed solution including lipid, membrane proteins and the surfactant, wherein the content of the surfactant in the mixed solution is made equal to or more than the sum of a maximum amount of the surfactant associating with the lipid and a maximum amount of the surfactant associating with the membrane protein.

Abstract: A liposome comprising a region of a lipid bilayer membrane with different membrane thicknesses, wherein each lipid bilayer membrane region is composed of a different lipid, and a thick membrane side in the region of the lipid bilayer membrane is formed of lipid having a phase transition temperature higher than that of the lipid forming a thin membrane side in the region of the lipid bilayer membrane. A proteoliposome, wherein the above-described liposome includes membrane proteins. A biochip, wherein the above-described liposome or the above-described proteoliposome is spread on a substrate. The above-described biochip, wherein the substrate includes at least one kind selected from the group consisting of mica, SiO2, SiN, Au and Pt.

Abstract: A protein chip including at least a substrate having a plurality of steps which are regularly arranged on one surface thereof; a plurality of metallic microstructures arranged in the steps; and a lipid vesicle in which an outer surface thereof is modified by a functional group and a protein is present in a lipid bilayer thereof.
