Tetyukhin from Zelenograd Institute of Physical Problems and the Moscow Institute of Physics and Technology in the field of biocompatible surfaces was published in journal of Russian Nanotechnologies. Among the materials which biocompatibility was improved, low-density polyethylene (LDPE) and polyurethane (PU) should be mentioned. To improve biocompatibility, a nanometer thick carbon coating was deposited on the polymers by using arc pulse-plasma sputtering of a graphite target. On the base of this technology, prostheses of blood vessels having improved biomedical characteristics were made. Furthermore, a technology for nanostructuring of poly(methyl methacrylate) (PMMA) surface in oxygen RF-plasma and a technology for smoothing PMMA surface by means of vacuum ultraviolet (VUV) or synchrotron radiation (SR) were developed. Also, the published article includes results of multistage treatment of titanium surface of dental implants. The suggested technology consists of three stages: rough sandblasting, chemical etching, and atomic layer deposition (ALD) of nanometer thick coating of titanium dioxide. Further reading

June 2010 – The chapter “Feature-oriented scanning probe microscopy” (FOSPM) written by Dr. R. V. Lapshin has been published in Encyclopedia of Nanoscience and Nanotechnology (edited by H. S. Nalwa, American Scientific Publishers). This chapter is a short review of the feature-oriented scanning (FOS) methodology that is applicable for high-precision, high-resolution scanning probe microscopy (SPM) and bottom-up nanofabrication. The FOS methodology can be employed in any instrument of SPM family: a scanning tunneling microscope (STM), an atomic-force microscope (AFM), a magnetic-force microscope (MFM), etc. It can also be used in a scanning electron microscope (SEM) or even it can simultaneously control a SEM and an SPM integrated in this SEM. The SPM under FOS control becomes essentially insensitive to temperature variations. The FOSPM is able to effectively organize a multiprobe bottom-up nanomanufacturing where nanoparticles, single molecules, or even separate atoms are used as construction blocks. The FOSPM allows a self-adjusting, self-calibrating, and self-testing; it transforms an SPM into the unmanned instrument that is able to operate according to the principle “run and forget”

October 2009 – “SPM in space”, Nano Digest, Journal of Russian Nanotechnologies: To obtain the adequate image of surface topography, Russian scientist Rostislav Lapshin from the Institute of Physical Problems (Zelenograd, Moscow) suggested a new approach called feature-oriented scanning (FOS). Applying a real-time surface recognition, counter movements, and some other techniques, repeated scanning of small neighborhoods of surface features located in the vicinity of each other are carried out. After that, the searched for topography image, free of noises and distortions, is assembled from the acquired fragments. In the method suggested, topography features of a surface are used as the reference points.
FOS method provides the measurement precision of lattice constants and crystallographic directions increased by orders in comparison with the conventional scanning. The method provides accurately localized tunneling and atomic-force spectroscopy measurements with high signal-to-noise ratio. Moreover, according to the author of the method, the feature-oriented scanning makes it possible to perform “delicate” manipulations with separate nanoparticles, molecules or even atoms at room temperature.
The analysis carried out at the Solid Nanotechnology Laboratory, where the scientist works, showed that the method of feature-oriented scanning that had proved successful in Earth conditions may also help solve a number of problems of using a scanning probe microscope in space – at a near-Earth station or for planet research. The point is that beside much higher measurement precision and spatial resolution, FOS permits to notably decrease the SPM sensitivity to temperature variations. Furthermore, the SPM under feature-oriented scanning control becomes a free-running instrument able of self-testing, self-adjusting and self-calibration. This story in Russian. Further reading
