Nanostructured multicomponent coatings based on thermolabile materials The multifunctional equipment with a hybrid ion-plasma discharge system designed by JSC «Research Institute for Precision Engineering» (Russia) allows to use the technology process for forming of multicomponent nanostructured coatings on plastics, which was created in Kurdyumov Institute for Metallophysics of the National Academy of Sciences of Ukraine in collaboration with Taras Shevchenko Kiev National University. The hybrid ion-plasma discharge system provides high film adhesion to a such material, preserving its required multicomponent composition. The process is promising for manufacture of medical-purpose devices.

Obtaining nanodispersed silicium dioxide from hydrothermal solutions The search for silica sources is caused by the demand for amorphous silicium dioxide on the part of modern industry, including the branches connected with nanostructured materials production. The expediency of silica separation from hydrothermal solutions is preconditioned by the possibility of complex usage of such resources. These solutions are a non-traditional source of mineral raw materials, including amorphous silica, which are formed from orthosilicic acid molecules as a result of interaction with aluminium silicate minerals of hydrothermal deposits rocks.

Thermal oscillations in micro- and nanomechanical systems Due to its simple measurement procedure the scanning probe microscopy is widely used by researchers in different fields: material science, physic, chemistry, biology. So far, in many cases the data obtained has a qualitative nature. Improvement of the measurement accuracy requires use of a non-destructive rapid method of determining the main characteristics of a probe – cantilever, which would provide immediate control of the probe state during the experiment process. This method is promising for application in cantilever-based sensor systems.

Metrological support of linear displacements measurement in the nanometer range In this paper the ways of providing the traceability of linear displacements measurements in the nanometer range to the primary standard of the meter using scanning probe microscope (SPM) are discussed. The design and principles of metrological SPM “NanoScan-3Di” equipped with the three-axes laser heterodyne interferometer are described. The features of using monocrystalline diamond tips having extremely high aspect ratio for surface profiling with SPM technique are considered with comparison to a conventional silicon cantilevers.

Work, success, admiration: results of the all-Russia school competition "From an infusorium to an atom" The schoolstudents` competition "From an infusorium to an atom’ devoted to the use of FemtoScan probe microscope with creative purposes is over. It was organized by JSC "Сenter of Promising Technologies" and RUSNANO School League. In the framework of the competition the participants were to propose their own views on images of the microworld, demonstrate creative thinking, fight for the right to take part in the second round. The elimination round included accomplishment of three tasks: receiving of an image, its processing with the special software environment On-line FemtoScan, creating of a presentation containing the images received and the author’s observations formed during the work.

Delivery nanosystem for immunocorrection of macrophages’ function at endometriosis The present work is the first stage of development of a delivery nanosystem for glucosaminyl muramyldipeptide (GMDP), an active compound of a number of immunomodulators. The results obtained have shown that silica particles functionalized by surface aminopropyl groups (APTES-modified silica particles) with a radius of 50 nm are the most suitable carriers for the preparation. It was demonstrated in vitro experiments that free GMDP and GMDP delivery nanosystems are able to correct impaired function of peritoneal macrophages of women with endometriosis. It has been revealed that the effect of the GMDP delivery nanosystem exceeds that of free GMDP, i.e. it allows to attain maximum stimulating effect of the immunomodulator in relation to the macrophages. This result may be used as a base for development of a new nanosomal drug`s formulation of the GMDP immunomodulator for effective therapy of endometriosis.
