Abstract: A polyelectrolyte-surfactant complex, a method of removing a toxic substance from contaminated soil or contaminated groundwater using a polyelectrolyte-surfactant complex and a method of making a polyelectrolyte-surfactant complex. The polyelectrolyte-surfactant complex is made from a complexated recombinant intrinsically disordered protein that has been electrostatically conjugated to an anionic surfactant to provide enhanced liquid-liquid phase separation properties.

Abstract: A method for modifying the properties of balsa wood comprises infiltrating a protein ionic liquid comprising polymerized dopamine into delignified balsa wood. A method of making an optically active protective coating comprises mixing protein ionic liquid comprising polymerized dopamine with ethyl acetate-based or water-based nail polish. A method of making a thermoplastic having biological activity comprises melting a thermoplastic; and blending a protein ionic liquid with the thermoplastic; and cooling the thermoplastic protein ionic liquid blend to a solid state. The thermoplastic is a hot glue stick. The protein ionic liquid comprises antibodies, enzymes, or fluorescent proteins.

Abstract: A method for creating a stable protein/antibody ionic liquid, comprising: (a) cationizing aqueous proteins/antibodies by addition of an excess of a positively-charged crosslinker in the presence of a coupling reagent; (b) purifying the cationized proteins/antibodies; (c) titrating the cationized proteins/antibodies with a corresponding biologically-compatible counter anionic polymer to create at least one protein/antibody cation/anion pair in aqueous solution until the cation/anion pair solution becomes negative by zeta potential measurement; (d) repeatedly dialyzing the protein/antibody cation/anion pair in water to remove excess anionic polymer using at least one molecular weight cutoff 7000 dialysis membrane; (e) lyophilizing the protein/antibody cation/anion pair to remove most of the water, forming a lyophilized solid; and (f) heating the lyophilized solid until a protein/antibody ionic liquid is generated. The antibody may be any desired antibody, and the anion may be any biologically-compatible anion.
