a) Polyelectrolytes employed for layer-by-layer assembly of nanometer-thick PEMs. b) Schematic illustration of the procedure used to fabricate PEM/PVA microfilms and apply them to wound-beds: (1) PEMs are assembled on PDMS sheets, (2) post-fabrication, PEMs are impregnated with silver ions that are subsequently reduced to silver-nanoparticles, (3) PVA solution is spin-coated over silver-loaded PEMs, (4) PEM/PVA microfilm is peeled from the PDMS sheet and (5) placed onto a moist wound-bed. 6) Dissolution of the PVA layer in the moist wound leads to (7) immobilization of the PEMs on the wound-bed.
