“…As reported in the study by Fedorets et al [20], consider the conditions for the formation of the levitating droplet cluster. In the case of an almost uniformly heated water layer, one can observe randomly moving small droplets over the water surface [21,22].…”

The main results of two decades of research on self-assembled clusters of microdroplets are reviewed, from the discovery of the phenomenon to current advances that can be applied to solve problems related to the airborne spread of dangerous pathogens and atmospheric pollutants. Special attention is paid to a flexible procedure for generating droplet clusters from a given number of nearly identical droplets of controlled chemical compositions with possible biological inclusions and effective ways of stabilizing the clusters. This is important for chemical and biological research in droplet microreactors. The physical mechanism of self-assembly of droplets in an ascending gas flow over a locally heated liquid layer is described in relation to the main methods of cluster stabilization: by infrared irradiation or by adding soluble but nonevaporating substances to a layer of evaporating liquid. The main module of a modern laboratory setup is presented.

“…Self-assembled clusters of condensed monodisperse water microdroplets levitating in an ascending flow of humid air over a locally heated water surface are a relatively recently discovered phenomenon. [1][2][3][4][5] Droplet clusters are similar to such classical objects of colloid chemistry as colloid crystals and dust crystals; however, they possess many unique features absent from the latter. It is known that organic chemical reactions are accelerated when reactants are present in microdroplets.…”
