A Deep Eutectic Solvent Thermomorphic Multiphasic System for Biocatalytic Applications.

The applicability of a thermomorphic multiphasic system (TMS) composed of a hydrophobic deep eutectic solvent (DES) and an aqueous potassium phosphate buffer with a lower critical solution temperature (LCST) phase change for homogeneous biocatalysis was investigated. A lidocaine-based DES with the fatty acid oleic acid as a hydrogen-bond donor was studied. Phase diagrams were determined and presented within this study.
