Estimating the term…
The invention relates to an antimicrobial surface having the formula SS−(V+2−W)X wherein: SS represents a solid surface, said solid surface comprising hydroxyl groups attached to a carbon atom in the unmodified state thereof; V+2 represents a doubly positively charged moiety having the formula —+NR2-T-NR2+—, or 1,4-diazoniabicyclo[2.2.2]octane; T represents a saturated or unsaturated straight-chain hydrocarbon having 1-24 carbon atoms; R represents a saturated or unsaturated hydrocarbon group having 1-24 carbon atoms; phenyl; or benzyl; W represents a saturated or unsaturated straight-chain hydrocarbon having 10-24 carbon atoms; and X represents an anion that balances the charge of V wherein a nitrogen atom of V replaces at least some of the hydroxyl groups.
An antimicrobial surface having the formula
A method for increasing the resistance to microbial growth of a material having on its surface (SS) a hydroxyl group covalently bonded to a carbon atom, the method comprising contacting the surface with a chemical composition capable of binding to said surface, thereby convening the surface to an antimicrobial surface having the formula
