The present invention relates to polyvinyl chloride (MP1) and (chloromethyl)polystyrene-merryfield (MP2), and curcumin photosensitizers (PS1), mesotetra(aryl)porphyrins, bacteriochlorins functionalized with chlorine or nucleophilic groups (PS2). , a polymer surface functionalized from a polymer or copolymer with an appropriate functionalization (X), which may be a halogen of a leaving group, including P2, chlorine or bacteriochlorin (PS3), in particular of the meso-imidazoyl-porphyrin type (MPn) -PSm) is explained. The structure of all photosensitizers in the present application includes a functional group (Y), which is an OH, SH or NH 2 nucleophile. The present application also describes the covalent bonding process of photosensitizer PS1-PS3 to functional polymeric material MP1-MP2 by nucleophilic substitution reaction to prepare MPn-Psm product. The products formed prevent the growth of microorganisms that can lead to serious infections, which is one of the leading causes of death in patients using these devices. |
