ABSTRACT:
The invention relates to an antimicrobial surface having the formulain-line-formulae description="In-line Formulae" end="lead"?SS−(V+2−W)Xin-line-formulae description="In-line Formulae" end="tail"?wherein:SS represents a solid surface, said solid surface comprising hydroxyl groups attached to a carbon atom in the unmodified state thereof;V+2represents 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; andX represents an anion that balances the charge of Vwherein a nitrogen atom of V replaces at least some of the hydroxyl groups.
