Solvent-free liquid proteins This new class of biomaterial has been shown to be a promising new technology where enzymes have been stabilized in non-aqueous environments. Using a variety of spectroscopic and scattering techniques, these novel biomaterials have been shown to allow for extreme enzyme thermal stability, stability against aggregation, and retained dynamics and enzymatic function all in the absence of water. Recently, we showed that protein-polymer surfactant nanoconjugates are soluble in both hydrophilic and hydrophobic ionic liquids, and demonstrated that biomolecule architecture can be preserved in the non-aqueous environment. Recent results involving the enzyme glucosidase demonstrated that the enzyme had significantly improved activity at 120 °C, and importantly, activity towards water insoluble cellulose. Projects in this area will focus on expanding the scope of these materials to new enzymes and processes, particularly plastic recycling. A. P. S. Brogan, L. Bui-Le, J. P. Hallett, Nat.
