Characterization of PEMs immobilized from PEM/PVA microfilms onto human cadaver skin dermis (GammaGraft), which was used to simulate the exposed dermis of a partial thickness wounds. Fluorescent micrographs of (a) microfilm with PEMs of (FITC-PAH/PAA2.5)40.5 on PDMS sheet, (b) PEM/PVA microfilm placed onto skin dermis with the PEMs facing the surface of the tissue, (c) PEMs immobilized on skin dermis after repeated rinsing with 1 mL PBS, and (d) PEMs retained on human skin dermis after 3 days of continuous incubation in excess PBS on shaker plates. e) Sustained release of silver ions into PBS from skin dermis modified with PEMs containing a range of silver loadings. The graph shows that the rate of silver ion release increased with the silver loading of the PEMs. Data presented as mean ± SEM with n≥4.
