Experimental setup of the 2D collagen membrane permeability tests. A: Permeability to distilled water in “dry-wet” conditions (mimicking a “dry” skin wound). B: Permeability to distilled water in “wet-wet” conditions (mimicking a “moist” skin wound). C: Permeability to proteins (BSA) in “wet-wet” conditions (mimicking a “moist” skin wound). D: Bacteria infiltration test. Red lines: 2D collagen membranes. I: insert of the modified Boyden chamber. W: well below the insert of the modified Boyden chamber.
