The liquid flows arising in a drop of a bioliquid, located on the glass surface. The relevance of the task is determined by the different applications: - nanotechnology-preparation of nanomaterials, education structures and nanoparticles in solutions of the nanoparticles, the self-assembly of nanoparticles; medical diagnosis - study of the functional properties of biological liquids, study of the processes of self-organization in a drop of a bioliquid; - development of modern methods of printing for inkjet printers.
