“…Independent experiments confirmed that the flows in pure liquids and in liquids with admixtures go in different directions [242,243]. In the multicomponent liquids of biological origin, the thermocapillary and solutocapillary effects can eliminate each other [60].…”

“…The flow is directed along the droplets base to its edge and along its surface towards to the center of the drop [54,114,225,228,244]. At the same time, experiments conducted with biological fluids exhibit opposite direction of flow [241][242][243]. According to Kistovich et al, Marangoni flow cannot generally occur during drying of the droplets of biological fluids; they suggest that the observed circular currents are caused by buoyant convection [105].…”

This review is devoted to the simple process of drying a multicomponent droplet of a complex fluid which may contain salt or other inclusions. These processes provide a fascinating subject for study. The explanation of the rich variety of patterns formed is not only an academic challenge but also a problem of practical importance, as applications are growing in medical diagnosis and improvement of coating/printing technology. The fundamental scientific problem is the study of the mechanism of microand nanoparticle self-organization in open systems. The specific fundamental problems to be solved, related to this system, are the investigation of the mass transfer processes, the formation and evolution of phase fronts, and the identification of mechanisms of pattern formation. The drops of liquid containing dissolved substances and suspended particles are assumed to be drying on a horizontal solid insoluble smooth substrate. The chemical composition and macroscopic properties of the complex fluid, the concentration and nature of the salt, the surface energy of the substrate, and the interaction between the fluid and substrate which determines the wetting all affect the final morphology of the dried film. The range of our study encompasses the fully wetting case with zero contact angle between the fluid and substrate to the case where the drop is levitated in space, so there is no contact with a substrate and angle of contact can be considered as 180 ∘ .

“…Moreover, the direction of flow can be opposite to a direction that is predicted by calculations for the pure solvent [146]. Independent experiments confirmed that the flows in pure liquids and in liquids with admixtures go in different directions [66,67]. In the multi-component liquids of biological origin, the thermocapillary and soluto-capillary effects can eliminate each other [25].…”

“…The flow is directed along the droplets base to its edge and along its surface towards to the center of the drop [126,128,130,134,147]. At the same time, experiments conducted with biological fluids exhibit opposite flow direction [66,67,146]. It has been suggested that during drying of the droplets of biological fluids, generally Marangoni flow cannot occur; the observed circular currents are caused by buoyant convection [68].…”

“…Even though numerous publications in medical literature have been devoted to pattern formation in biological fluids during their drying, physicists, chemists and mathematicians began to pay attention to this problem only recently. During the last decade, several groups of physicists began to actively publish work in this direction [64,[66][67][68]. A significant part of the publications from Russia belongs to only two research groups, namely a team from Astrakhan State University [49,[69][70][71][72][73][74][75][76] and a team from Insitute of Applied Physics RAS [18,50,51,60,[77][78][79][80].…”

This short review is devoted to the simple process of drying a multi-component droplet consisting of a complex fluid containing a salt. These processes provide a fascinating subject for study. The explanation of the rich variety of patterns formed is not only an academic challenge, but a problem of practical importance, as applications are growing in medical diagnosis and improvement of coating/printing technology. The fundamental scientific problem is the study of the mechanism of micro-and nanoparticle self-organization in open systems. The specific fundamental problem to be solved, related to this system is -the investigation of the mass transfer processes, the formation and evolution of phase fronts and the identification of mechanisms of pattern formation. The drops of liquid containing dissolved substances and suspended particles are assumed to be drying on a horizontal solid substrate. The chemical composition and macroscopic properties of the complex fluid, the concentration and nature of the salt, the surface energy of the substrate and the interaction between the fluid and substrate which determines the wetting, all affect the final morphology of the dried film.
