Organic nanoparticles from microemulsions: Formation and applications

Abstract Microemulsions have already been recognized as convenient templates for nanoparticle synthesis. Spontaneous formation of the compartmentalized domains within the microemulsions leads to facile and low-cost preparation processes. In the past, microemulsions were mainly explored as precursors for the synthesis of inorganic nanoparticles. However, there is a constantly growing number of publications offering to exploit these systems to produce organic nanoparticles, and in recent years, a variety of methods have emerged in this field. The aim of this review is to survey the methods recently used to produce organic nanomaterials from microemulsions, and to give a perspective on particle design possibilities that can be achieved by various techniques. The structure of the initial microemulsion system, the chemical and technical aspects of preparation, the nature of additives and surface active agents, as well as the possible outcomes in terms of final particle characteristics, will be discussed for the various methods.
