Claim 16:
17. A method of making a protein film on a substrate, the method comprising:
depositing a protein solution comprising anionic bovine serum albumin on the substrate, to form a protein film on the substrate;
dipping the protein film on the substrate in perfluoroperhydrophenanthrene (PFHP) and heating the PFHP while the substrate is immersed therein to maintain a temperature of about 140° C. to about 200° C. for about 1 to about 30 minutes, to stabilize the protein film on the substrate;
removing the protein film on the substrate from immersion in the PFHP; and
washing the protein film on the substrate to remove any residual at least one organofluorine compound present following removal,
wherein the protein film on the substrate is a hydrophilic protein film and is free of the PFHP following the removal of the protein film on the substrate from the PFHP.
