Patent ID: 7625579

Claim:
A substrate having a plurality of immobilized furanone moieties associated with at least part of a surface of the substrate, wherein the furanone moieties are derived from at least one compound selected from the group consisting of a furanone compound and an analog thereof wherein the furanone moieties are covalently bonded to functional groups on the surface of the substrate; and wherein the furanone compound is of the formula wherein R 1 is a moiety selected from the group consisting of H, halogen, formyl, carboxyl, cyano, ester, amide, alkyl, alkoxy, oxosikyl, alkenyl, alkynyl, aryl and arylalkyl, which moiety may optionally be substituted by one more substituents; and/or interrupted by one or more hetero atoms; and/or straight chain, branched chain, hydrophobic, hydrophilic and/or fluorophilic; R 2 , R 3 and R 4 are independently or all H or halogen; and represents either a double bond or a single bond.
