Dispersive liquid–liquid microextraction (DLLME) is a new microextraction technique with a high potential in sample pretreatment. This article presents the state of the art and discusses the prospects of DLLME. A contextual description of sample pretreatment techniques ranging from liquid–liquid extraction to microextraction is provided for the readers to gain a better understanding of the topic. General and specific concepts of the fundamental theory of DLLME that are required to understand and implement the technique are described, and examples of recent innovations and applications are provided to illustrate its potential for the determination of a wide range of compounds in various types of matrices. Finally, its combined use with other pretreatment approaches, and separation and detection techniques, is also discussed.
