Abstract:
1. An antimicrobial surfactant polymer, comprising: a) a polymeric backbone of repeating monomeric units; b) a plurality of hydrophobic side chains comprising from about 2 to about 18 methylene groups, the plurality of hydrophobic side chains being linked to the polymeric backbone by one of the group consisting of ester linkages, secondary amine linkages, amide linkages, and combinations thereof; c) an antimicrobial peptide comprising Nisin having an aldehyde linkage; d) a first hydrophilic side chain and a second hydrophilic side chain having spaced apart proximal and distal chain ends comprising reactionable di-aldehyde terminated polyethylene glycol molecules, wherein the proximal end of the first and second hydrophilic side chains are linked to the polymeric backbone by one of the group consisting of an ester linkage, a secondary amine linkage, an amide linkage, and combinations thereof; and e) wherein the distal end of at least one of the first or second hydrophilic side chains is linked to the antimicrobial peptide by an aldehyde linkage.
