Abstract: The present disclosure provides a pH-sensitive membranolytic polymer material and a preparation method and application thereof. The pH-sensitive membranolytic polymer material has the structure shown in Formula (I). At normal physiological pH, the polymer material is hydrophobic neutral, and can be self-assembled into PEG coated nanoparticles with weak interaction with cell membrane; when the pH decreases, the polymer material can be protonated to form an amphiphilic structure consisting of hydrophobic domain and cationic domain, which has strong interaction with the cell membrane and strong membranolytic activity, so the polymer material can kill tumor cells or bacteria efficiently and selectively.

Abstract: A resin composition includes a resin A, a resin C, and a solvent. The resin A includes a sulfonic-acid-group-containing structural unit in an amount exceeding 5 mol % with respect to total structural units included in the resin A. The resin A has a content of a fluorine atom of 30 mass % or less with respect to a total mass of the resin A. The resin C includes a fluorine atom in a larger content per unit mass than the content of a fluorine atom per unit mass in the resin A. A content of the resin A in the resin composition is lower than a content of the resin C in the resin composition in terms of mass.

Abstract: The present invention provides a bio-electrode composition including: a resin containing a urethane bond in a main chain and a siloxane bond in a side chain; and an electro-conductive material, wherein the electro-conductive material is a polymer compound having one or more repeating units selected from fluorosulfonic acid salts shown by the following formulae (1)-1 and (1)-2, sulfonimide salts shown by the following formula (1)-3, and sulfonamide salts shown by the following formula (1)-4. This can form a living body contact layer for a bio-electrode that is excellent in electric conductivity and biocompatibility, light in weight, manufacturable at low cost, and free from large lowering of the electric conductivity even when it is wetted with water or dried. The present invention also provides a bio-electrode in which the living body contact layer is formed from the bio-electrode composition, and a method for manufacturing the bio-electrode.
