Antibacterial activity of a photosensitive hybrid cellulose fabric

Abstract

We report the preparation of a cellulose fabric bearing derivative protoporphyrin IX units covalently attached to the cellulosic backbone of a fabric. The use of Ce (IV) redox system radical polymerization was used to polymerize of methacrylic acid (MAA) onto cotton material and to obtain cotton-g-polyMAA. Attachment of the photosensitizer, protoporphyrin IX (PpIX) amino derivative on cotton-g-polyMAA has been realized successfully by classical peptidic covalent link. The modified surfaces have been characterized by ATR-FTIR, DRUV, TGA, SEM methods. Under visible light irradiation, protoporphyrinic cotton showed an antibacterial activity against, Staphyloccoccus aureus. This concept is very promising in the field of bacterial decontamination (sterile area, hospital equipments, etc.).
