Natural-based chiral task-specific deep eutectic solvents: A novel, effective tool for enantiodiscrimination in electroanalysis

, 2021
Deep Eutectic Solvents (DESs) offer advantages similar to ionic liquid (IL) ones, with easier and more sustainable synthesis; moreover, bio-based DESs often include chiral components, surprisingly underexploited.
