Caption

Figure A shows the fabrication process of ultrathin film from small intestine submucosa. Figure B is a scanning electron microscope image showing the thickness comparison between the untreated (78.5 μm) and peeled-off small intestine submucosa (8.5 μm). Figure C shows the thickness of ultrathin film by repeated peeling (about 100nm). Figure D shows ultrathin film on a silicon substrate.
