The incessant effort to perform a more sustainable chemistry has brought about the development of new materials that accomplish the principles of the green chemistry. In this context, deep eutectic solvents (DESs) have surged as one of the most promising alternatives to the use of toxic organic solvents. Their unique properties have led to a huge development of these materials and a sharp increase of their applications in the recent years in analytical chemistry. They have been applied in sample preparation and analytical techniques. The quantity of new information generated from studies associated with DESs is enormous and needs to be continuously revised. In this review, the most relevant aspects related to the application of DESs in the last five years (2016-2020) have been compiled and critically discussed in order to provide a global view about the advantages and limitations of these new materials in the area of analytical chemistry.

通过不断努力以实现更具可持续性的化学反应，导致了开发出符合绿色化学原理的新材料。在这种情况下，深共晶溶剂（DES）激增为使用有毒有机溶剂的最有希望的替代方法之一。它们的独特性能导致这些材料的巨大发展，并且近年来在分析化学中的应用急剧增加。它们已应用于样品制备和分析技术中。与DES相关的研究产生的新信息数量巨大，需要不断修订。在这篇评论中
