Nanotribology is an exciting area of tribology science. It is rather short history of this important branch of tribology. The starting point was the invention of Atomic Force Microscopy (AFM) which was very sensitive instrument to investigate friction on atomic scale. The wide area of AFMs family enables nowadays to perform complete interdisciplinary research on atomic and nanometer scale to understand tribological, mechanical and other physical and chemical phenomena occuring on sliding interface. The adhesion, friction, wear and mechanical studies became common in many tribological labs in the world. The understanding of surface phenomena is important to investigate the tribological behaviour of micro- and nano-tribosystems. The use of such powerful instrument like AFM is together with other devices like Scanning Tunneling Microscope (STM) and Surface Apparatus (SFA) enables to study topography, adhesion, friction, wear and other properties. The rheological phenomena on nanoscale in particular in lubricating nanosystems are of great interest of tribologists to understand in particular transition from static to kinetic friction on atomic and nanometer scale. Many applications of nanotribology in magnetic recording technology. Micro Electro Mechanical Systems (MEMS) and Nano Electro Mechanical Systems (NEMS) technology and in nanoimprinting technology are now of subject of many projects in the world. Future trends in nanotribology relate mainly to understand the process of energy and matter dissipation on atomic scale. The final aim of nanotribological research is to construct frictionless and wear less tribosystems in nanotechnology. Nanoimprinting technology except MEMS/NEMS technology are in particular very interesting area of the nanotribological studies. Very important is to understand friction in biological systems. The studies of flagellum motor or/and ATF - phase in biological molecular systems can lead us towards the biomitecis and adaptronics i.e. construction of ideal nanosystems. The relationships between friction and wear on atomic scale is of great importance to be understood. The possible way is molecular dynamics modeling by increase of the number of atoms involved in the process. The time scale in such modeling should be as much as possible wide. The application of effective supercomputers in such study is necessary. Tribochemistry and termodynamics are important approaches to be taken into consideration in the studies of atomic and nanometer scale tribosystems. The rapid progress in nanotribology is necessary for the development of nanoscience and nanotechnology. The nanotechnology enables to construct ideal systems on any scale. Probably the way proposed by K.E. Drexler by the use of mechanosynthesis and single atoms as "bricks" in construction of technical systems is the best way which is opening before us.
