The development of methods for controlling the architecture of ensembles of micro- and nano-particles via affecting the processes of their self-assembly in a drying drop of solution is an urgent problem in modern fundamental (theory of ordering in a dissipative system) and applied (design of microstructures and materials with new properties) science. The elucidation of the role of various factors in the processes of self-assembly allows for an elaboration of the foundations of a predictable impact on the system in order to achieve the desired result, which is characterized by a particular morphology (the distribution of particles in a substrate and structure) of the particle ensembles. The physical models of self-assembly are considered, and the results of modeling and experimental investigations of ordered ensembles of micro- and nanoparticles are reviewed. Particular attention is drawn to the method of dissipative particle dynamics. © 2013 Pleiades Publishing, Ltd. Source

The physical and computational model of self-assembly in an evaporating microdrop of solution several hundreds of picoliters in volume is described as a further development of dissipative particle dynamics (DPD) methods used in systems with a changeable volume. The simulation results are compared with experiments on the aqueous solutions of polystyrene colloid particles. © 2011 Pleiades Publishing, Ltd. Source

This article discusses the key features of new image-analysis systems, based on electronic-table technology for working with images. It is shown that image-analysis systems can be transformed from the category of visualization systems into the category of measurement facilities. Examples are given of the operation of the SIAMS image analyzer for analyzing the images of microstructures in a wide range of scales, obtained by various methods of digital microscopy. © 2011 Optical Society of America.
