Antimicrobial potential of natural deep eutectic solvents

Letters in Applied Microbiology, 2022
Abstract Natural deep eutectic solvents (NADES) are a new class of green solvents, which can solubilize natural and synthetic chemicals of low water solubility. NADES are mixtures of two or three compounds of hydrogen bond acceptors and hydrogen bond donors.

Bio-derived feedstocks for natural deep eutectic solvents

Proceedings of 32nd Annual Meeting of Association for Advancement of Industrial Crops, 2021
Deep eutectic solvents represent mixtures, where two or more compounds interact through hydrogen bonding (i.e. H-bonds) and dramatically reduce their melting point. As a result, even some solid substances can become liquid just by being mixed together without any chemical reaction, only by acting as H-bond donors or acceptors.

Green solvents from ionic liquids and deep eutectic solvents to natural deep eutectic solvents [PDF]

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.

Natural deep eutectic solvents as biofilm structural breakers

Water Research, 2021
Natural Deep Eutectic Solvents (NADES) are composed of supramolecular interactions of two or more natural compounds, such as organic acids, sugars, and amino acids, and they are being used as a new media alternative to conventional solvents. In this study, a new application of NADES is presented as a possible technology for biofilm structural breaker ...
