Center of Nanoelectronics and novel materials provided services for BSUIR laboratories and third parties for the measurement of surface topology, sizing and number of embedded clusters using an atomic force microscope. Conductivity and other electrical characteristics investigated using an atomic forcemicroscope (AFM). Measurements of biological objects (blood and bile) were carried out for the Emergency Hospital, anodic alumina films containing nickel and copper clusters were studied for Sofia University (Sofia, Bulgaria) as well as the Si/Ge nanostructures.
Complexresearch of BSUIR specialists (V. E. Borisenko team) and "Integral" for the development of AFM probes using planar technology is successfully conducted. A complex of workson the development of manufacturing AFM probes are carried out. The ITMO NASB developed a technology of modifying of silicon commercial probes tips by single nanotube and modeling by numerical methods of molecular dynamics processes of their contact with the sample.

The research team fromthe Institute of Physics (V. M. Jasinski team) and IHMT NASB completed project to build the first domestic scanning near-field optical microscope in which the AFM modification was created based on tuning fork sensor, realizing scanning in dynamic lateral forces mode.
Scientists from IHMT NASB (S. A. Chizhik team) completed a number of research of equipment and techniques on the basis of the AFM, which will allow to control the nanolayers and nanoobjects in the future for the purposes of microelectronics, materials science and bioengineering. There are the following developments among them: the methods of static and dynamic force spectroscopy, non-destructive nanotomography, oscillating nanotribometry, technology of membrane capillary transport to modify the tip of the probe. The models of micro- and nanoindentation of materials using AFM are actively developed (T.A. Kuznetsova, A.L. Khudoley). A theory of the dynamic AFM mode is developed too (S.O. Abetkovskaya team). Methods of cell elastography are created (E.S. Drozd team).
A new method to determine the viscosity and elasticity modulus, tangent of the angle of mechanical loss and the relaxation time of the polymer and biological materials was developed and patented by the research team from IHMT and IAP NASB. Scientific novelty of the results obtained lies in the simultaneous determination of the coefficient of viscosity and elastic indentation modulus at different loading rates. The method is intended for research using AFM. A device for the measurements of the viscosity in thin layers on the basis of AFM was developed. The device is developed for the Gdynia Maritime University (Poland).
An optical system for the analysis of living cells by optical microscopy and AFM scan engine system, an experimental model of the complex - a miniature bioreactor, AFM scanning module and control electronics are developed. A project to create a complex “miniature bioreactor - an optical microscope - the atomic force microscope” and software for long-term analysis of living cells is performed (S. A. Chizhik teamand others). Methods for producing cell cultures that are adapted to grow in a miniature bioreactor are also developed. A project on AFM based nanometrology is performed in cooperation with BelSIM specialists (A. E. Demidova team).
An automated experimental facilityfor the formation of multimolecular layers and films is created by specialists from "MICROTESTMACHINES" and Institute of Chemistry of New Materials of NASB (V. E. Agabeyov team). The facilityallows modification of the surface, altering its properties (optical, electrical, etc.) to create insulating and conductive ultrathin films, protective coatings and other elements as molecular electronics solid surface, and a flexible polymer backbone. The innovation will allow development new approaches to formation of composite structures with desired properties (durability, conductivity, magnetization) for the creation of modern biosensors, biomarkers and microcapsules for medicine.
A technology offormation of multilayer composite materials based on tin and ultrafine carbon units is developed by specialists from BSUIR and GSU (A. A. Khmyl and A. V. Rogachev). These coatings effectively replace the protective coverings of gold, platinum, silver in electronic products, as well as improve the mechanical properties of friction machine parts and mechanisms.
A technological complex for the production of fullerenes by means of laser and arc evaporation is created in BSU jointly with the "Planar". There is a pilot technology for production and processing of fullerene soot and carbon nanotubes, methods of preparation and diagnosis of materials, films and coatings with fullerene. However, the limiting factor in the way of industrial use of these materials is still their high cost.
