In this work we give an overview of researches, conducted in the framework of the project RFBR-BRICS, together with groups from Brazil, Russia, India, China and South Africa on the development of new technology nanoassembly «bottom-up» various devices for nanoelectronics, nanosensors, biomedicine and basic research based on the use of new functional materials with phase transitions and new physical effects. The Russian group carried out work on improving the nanomanipulation system based on nanotweezers made of Ti2NiCu alloy with shape memory effect. A new design of the control system is proposed, which reduces the control power of the resistive heater and reduces the uncontrolled drift of the nanotweezers by up to 5 times. In the process of joint technological, design and physical research in the field of nanomanipulation and nanoassembly technology, the following main results were obtained by the participating groups. The Indian group, together with the Russian group, studied the melting processes at the micro-level of dimensions, and showed the possibility of manipulating a drop of molten gallium with the help of electromigration and the formation of contact chains for nanoassembly without the use of lithography. Also, the Russian and Indian groups studied the possibility of individual manipulation of microparticles in the liquid. The Chinese group, together with the Russian one, manufactured and tested a prototype of a spin-injection microwave electromagnetic oscillator for nanosensory applications. The Russian and South African groups produced "bottom-up" nanoassembly of carbon nanomaterials, such as CNT, decorated with magnetic ions and nanodiamonds ring structures, and they were searched for quantum effects such as quantum oscillations of transport properties and superconductivity. The Brazilian, Chinese and Russian groups jointly produced prototypes of nano-bio-sensors based on field-effect transistors made of suspended semiconductor nanowires using the bottom-up nanosembly method. Two original approaches to nanoassembly were used: a variant of the traditional scheme with liquid transportation of nanowires and an approach based on three-dimensional manipulation using the nanotweezers with a shape memory effect.
