Abstract

A methodology is developed and validated whereby a cotton fabric is impregnated with a photosensitive hydrophobic N-alkyl-polyethylenimine, followed by its covalent immobilization triggered by ultraviolet light. The resultant fabric efficiently kills on contact waterborne pathogenic bacteria E. coli and S. aureus.
