| Outline of Final Research Achievements |
The protein, as a precisely structured functional molecule, has broad potential in material science. However, a general and versatile method to materialize the protein has not yet been established.
In this study, high-protein content (120 - 310 mg/mL), water-immiscible liquid material was developed by simple mixing of an aqueous protein solution with a solution containing specific amounts of both anionic- and cationic surfactants. The material has a hierarchical structure whereby the protein and the ionic surfactants are electrostatically complexed and yields an ordered fluid through moderate hydrophobic interactions. The material contains water inside associated with the hydrophilic part of the surfactants and, importantly maintains the function of the native protein.
These significant features of this material are advantageous for practical use of protein as structural and functional material.
