Abstract:
1. A fabrication method for a flexible porous free-standing protein membrane formed by cross-linked protein, comprising: (1) a first step of mixing metal hydroxide nanostrands and protein to obtain a composite made of the protein and the metal hydroxide nanostrands; (2) a second step of forming a membranous body formed by said composite made of the protein and the metal hydroxide nanostrands, and mutually cross-linking said protein by a bifunctional cross-linker; and (3) a third step of dissolving and removing said metal hydroxide nanostrands whose diameters are 2-3 nm to produce a flexible porous free-standing protein membrane containing channels, wherein a thickness of the flexible porous free-standing protein membrane is 10 μm or less.
