“…Several reviews [15-17, 20, 288, 289] and books [5][6][7][8] based on pattern formation during desiccation published within the short span of just four years confirm the intensely growing interest in this subject. Exploiting the full potential of this topic in basic science research and applications needs involvement and interaction between scientists and engineers from disciplines of physics, chemistry, biology, medicine, and other related fields.…”

“…Dried droplets of blood and blood serum show characteristic crack patterns for patients suffering from anemia, hyperlipidemia, and other disorders [7,21]. A related field where droplet patterns are of importance is forensics related to crime investigation [7]. More such areas are biopreservation [216,274] and high-throughput drug screening, where pattern formation in the drying sample is not desirable [60].…”

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 ∘ .

“…In the last two decades there has been a great deal of study on the drying mechanism of evaporating droplets and their dried patterns [1][2][3][4]. Apart from an understanding of the underlying principles of science, the important applications of this research area in different industries-from printing, paint, lubrication, pharmacy and cosmetics, medicine and microfluidics, to providing tailored templates for micro-devices [5][6][7][8][9], remain the primary motivation behind these studies.…”

The patterns left by desiccating droplets of colloidal solutions form an integral part of a gamut of applications in technology, medicine and fundamental science. While almost all attention is reserved for understanding flow dynamics of drying droplets and the resulting dried droplet pattern with respect to variation of a host of parameters, there is almost a total absence of any discussion on the importance of the ‘mixing methods’ of solute and solvent during solution preparation. We demonstrate in this work, that desiccation patterns of colloidal solutions show an amazing variation in details, depending on the manner of solution preparation. The variation is achieved by simple mechanical treatment, namely magnetic stirring and ultrasonication, and for different stirring times. The suitable explanation of the striking variation in the dried droplets on both hydrophilic and hydrophobic substrates lead us to propose that the stirring time corresponding to a particular method adopted for solution preparation, results in varying degrees of paring of aggregates. We establish that a homogeneous colloidal solution can only be achieved by mixing for a minimum time t std , that is a function of a particular mixing procedure and a given solute-solvent combination. The prepared solution may then be used in different applications to obtain faithful standard results.
