Deep eutectic solvents for redox biocatalysis

Journal of Biotechnology, 2019
Deep eutectic solvents (DES) are a class of neoteric solvents used in multiple applications amongst which biocatalytic processes. Due to its simple preparation, low cost and inherent biodegradable properties, its use as a non-volatile biocompatible co-solvent with both whole cells and isolated enzymes has displayed increased enzyme activity and ...

Green solvents from ionic liquids and deep eutectic solvents to natural deep eutectic solvents

Comptes Rendus. Chimie, 2018
Natural deep eutectic solvents (NADESs) are defined as mixtures of certain molar ratios of natural compounds such as sugars, organic acids, amino acids, and organic bases that are abundant in organisms. The melting points of these mixtures are considerably lower than those of their individual ingredients and far below ambient temperature.

Properties of Polyvinylpyrrolidone in a Deep Eutectic Solvent

The Journal of Physical Chemistry A, 2016
Deep eutectic solvents (DES) are mixtures of two or more components with high melting temperatures, which form a liquid at room temperature. These DES hold great promise as green solvents for chemical processes, as they are inexpensive and environmentally friendly.
