Antimicrobial finish of polyethersulfone-membranes: Sticking photosensitizers like marine mussels would do

New Paper released in Advanced Engineering Materials.



A chlorin-based photosensitizer, known from photodynamic therapy was derivatized to realize antimicrobial finishes for water-filtration membranes. The introduced catechol moieties known from adhesive systems of marine mussels, improved the coating stability and affect both positioning and packing of the photosensitizers, to retain singlet oxygen production. The irradiation of coated membranes by visible light significantly reduces bacterial growth of both gram-positive and gram-negative strains.
