[Natural nanotechnologies in living cell: view on the problem]

Literature and research data concerning natural nanotechnology in living systems is summarized in this article. Over millions of years, nature has evolved complex processes controlling the functioning of living organisms. Using the principles of nature to create new tools and technologies is the current direction in the development of "smart" materials and systems. Physiologically active substances (amino acids, neurotransmitters, vitamins, albumin, ATP, fructose, DNA, RNA, fibrinogen, glutathione and others) are nano in size. Biological membranes, ion channels, nanopores, colloidal solutions of the body (blood, interstitial fluid) are nanostructures. The basic principle of nature reads: small tools make great work. In biological materials natural principle of high efficiency and minimum energy consumption is carried out due to the existence of natural nanotechnology that needs more study. In efficient energy-consuming processes during the evolution gradually disappeared and were replaced by more effective. The study and experimental proof of natural nanotechnology will bring a better understanding of the laws of physiological functioning of organs and those of metabolic processes that maintain life. The ability to reproduce biological form with nanoscale precision will find application in tissue engineering, drug delivery, modeling and development of sensory and immune systems, visualization and diagnostic tools. Natural nanotechnology is highly effective, low energy-consuming, causes a rapid flow of vital processes in the body, the ability to quickly response to external positive and negative factors. Not all data presented in this paper is experimentally confirmed, it may be controversial and require further extensive research by specialists of different areas to determine the role of nanotechnology and nanomechanisms in physiological, biochemical, immunological, genetic and other processes in living systems.
