Development of new biotechnological foundations for construction of test-systems for identification of viral and bacterial infections’ causative agents on the basis of recombinant proteins of human and animals viruses.
In the Section of interferon and immunomodulators the new direction in interferonology was for the first time theoretically substantiated, experimentally proved and clinically approved – namely identification of antibacterial efficiency of interferon preparation under bacterial infections (sepsis, pyoseptic processes, salmonellosis, toxicoinfectious shock etc.). We formulated the notion of interferon system and identified direct and reverse connections between this system and immune and neuroendocrine systems of an organism. Researchers of the Section developed a methodology of identification of interferon status of an organism and this allows for determining the role and place of interferon system on the level of population.
Researches made during last 5 years established fundamental foundations of interferon system functioning under pre-tumor and tumor diseases, caused by carcinogenic papilloma viruses; allowed to develop new approach to purposeful stimulation of interferon generation based on the original concept of directed construction of substances – inductors of interferon; brought new information about general architecture and morphogenesis of complex human and animals viruses ascribed to one taxon and this is related to understanding of fundamental virology problems as regards evolution of phyto- and animal pathogenic rhabdoviruses. Using modern methods of immune biotechnologies researchers of the Section obtained first and second generations interferon preparations as well as prospective interferon inductors. Individual indications and contraindications for clinical use of interferon and its inductors under viral, bacterial and other pathogenic processes were identified.
The section has fruitful cooperation with a number of laboratories from the USA, Canada, Russia, Israel, Iran, Slovakia and other countries. The employees of the section defended 7 Doctoral and 22 candidate dissertations, published 10 monographs, 4 practical handbooks, 4 methodology recommendations for Ministry of Health of USSR and Ukraine, published the first in Ukraine “Basic Virology” textbook, have 68 copyrights and patents of USSR, Ukraine and Russia.

Pavlov silver medal (Russia, 2002), golden medal of World Organization of Intellectual Property (Switzerland, 2002), Honorary diploma of Kyiv City mayor (2003) and diploma of Verkhovna Rada of Ukraine (2007) , O. Bogomolets award of NASU, O. Palladin award and with three awards of President of Ukraine for young scientists.
Why V. Bakul Institute of Superhard Materials?
V. Bakul Institute of Superhard Materials (ISM) of NASU celebrated its 50th anniversary in 2011. ISM was created in 1961 by the government decree under auspices of State Plan of Ukrainian SSR. In 1972 the ISM was transferred to the structure of the Academy of Sciences of Ukrainian SSR. In the very short terms personnel of the Institute using the laboratories of the Institute of High Pressure Physics of Academy of Sciences of USSR developed the technologies for industry-scale production of synthetic diamonds and organized the production of synthetic diamonds and instruments from them. In 1960s-1970s highly efficient instruments made of superhard materials were introduced in thousands of industrial enterprises of different fields in USSR and other socialistic countries.
In the short period of time the ISM became one the world’s leading centers in material science in the fields of extra high pressures and extra high temperatures. The ISM staff deservedly occupies one of the most prominent positions in the world regarding development of fundamental researches in physicalchemical grounds for the synthesis of superhard materials, development of methods of studying their internal structure and set of physical and chemical properties.
V. Bakul ISM of NASU cooperates with research and production centers of superhard and nanomaterials in many foreign countries including USA, Japan, Germany, UK, RSA, China, Poland, Israel and others. Products with ISM trademark are widely known in the world; there is licensed production of ISM products in Ukraine, Belarus, Russia, Bulgaria, Serbia, Hungary, Germany, China, South Korea and other countries.
The Institute is comprised of 12 main scientific departments, 1 research laboratory and 4 auxiliary departments and an administrative section. 406 people work in the Institute, among them 206 researchers including 84 Candidates of Sciences, 32 Doctors of sciences, 2 members of NASU and 5 Corresponding Members of NASU.
Some of research results of the ISM are of world-class in material science for example such as synthesis of high-purity monocrystals of diamonds of big size and perfect structure (1993, Patent of Ukrain No2), production of different color diamonds (2006); synthesis of superconductive magnesium diboride with high level mechanical properties for use in construction (2006); development of constructions for movable endoprostheses of joints on the basis of artificial sapphires, titan-silicon alloys, aluminum and zirconium oxides (2008-2011) Since 2006 the ISM has been successfully developing ecologically safe nanotechnologies of industrial production of colloid nanometal solutions in liquid mediums such as natural biopolymers (chitosan, dextran), high-molecular substances (PEG, PVS), glycerine, natural and artificial oils etc. These provide master-butches for creation of new generation nanodisinfectants which would easily modify products of personal hygiene, pharmacological preparations, food products and packaging materials.
Center for collective use of devices “Analytical center of research and nano-diagnostics of superhard material” functions within the ISM. Since the establishment of the Institute more than 8 thousand articles have been published by its staff, the Institute has more than 3000 of copyrights and patents, 20 licenses. For the last decade the ISM have taken out 335 patents and carried out seven license agreements. The Institute became a coordinator of the European program START that united centers of perfection in the field of material science from France, Poland and other EU countries.
The Institute suggests development and introduction into nutrition of ion-plasma nanodispersion of metals and production of high efficiency industrial equipment for production of concentrated nanoadditves in the wide range of mediums – natural biopolymers (chitosan, dextran etc.), high molecular substnces (PEG, PVS), polysaccharides, food glycerine etc.
Production of high concentration suspensions of nano-structure material on the basis of organic and non-organic liquids (so called “master-butches”) which are added to numerous products of disinfection, personal hygiene products, pharmacology products, food products and drinks in order to improve their consumption properties has become a very important and independent area of nanotechnologies research in the world. Of particular prospect is production of oligodynamic metals (Au, Ag, Pt, Fe, Cu) concentrated nanosuspensions in liquids which are the most frequently used ingredients in modern home chemical products, products of personal hygiene and food products and easily get mixed up with them without need to change the traditional production. Use of nanomaterials most frequently demands their dissolution in different liquids in order to inject a homogenous solution to the final product. For example, an important way of using nano-additives in medicine is a delivery through dissolution of active nanoparticles in organic liquid mediums. Since most of nanomaterial solutions are thermodynamically unstable, they quickly agglomerate and coagulate and that makes them non-effective for practical use. Most of metal nanoparticles produced on industrial scale in the form of nanopowder and thus they demand multistage processes of colloid chemistry for transforming them into liquid solutions: moistening nanopowders with liquids, destruction of agglomerates using different technologies and their stabilization in solutions in non-coagulated form by adding of special dissoluble agents.
The Institute of Superhard Materials developed an efficient single stage method for production of high concentration colloid solutions (suspensions) of nanometals using water-soluble and water insoluble liquid mediums where plasma beam in vacuum disperses metals and in the same cycle implants nanoparticles to vacuum cleaned liquids. Therefore, both in Ukraine and in the world complex “wet-dry” technologies which utilize productive physical methods of metal dispersion along with engineering solutions for implanting metal nanoparticles into liquid mediums in one technological cycle became the most important practical method for production of metal nanoparticles solutions in the wide spectrum of liquids (master-butches). In Ukraine the “Rubin” company from Kharkiv, which owns numerous Ukrainian patents in nanotechnologies using silver nanoparticles, is an industrial manufacturer of commercialized silver nanocoatings produced using gas-core synthesis technology. In E.O. Paton Electric-Welding Institute an industrial technology of obtaining nanoparticles for magnetic liquids through electron beam evaporation and condensation in vacuum was developed.
During 2007-2011 within grants of NASU V. Bakul Institute of Superhard Materials together with E.O. Paton Electric-Welding Institute developed the new technologies of metallocolloids production. Under supervision of NASU academicians M. Novikov and D. Dudko a technology and equipment for ecologically safe single stage plasma nano-dispersion of metals in vacuum with implanting them into liquid media in a single technological cycle were developed.
This technology in particular was practically used for production of high concentration nanosuspensions of silver in liquid water-soluble mediums for nanomodification of new generation bactericides for disinfection of contact surfaces, tissues, filters and so on.
Introduction of complex “wet-dry” technology of localized ion-plasma nano-dispersion of electroconductive materials in the V. Bakul IMS of NASU and run of pilot production plant for production of concentrated (up to 1000 mg per liter) nanosuspensions of metals (Ag, Cu, Fe, Mo, Pt, Pd, Au etc.) and for production of concentrated nano-additives in the wide range of liquid medium such as natural biopolymers (chitosan, dextran), high molecular substances (PEG, PVS), polysaccharides, food glycerine with output rate up to 10,000 liter per year. Control over size, form, distributioin of produced nanoparticles as well as high productivity of dispersion (at least ten times higher than of known methods of wet synthesis of nanoparticles) allows to develop an industrial technology of nanometal colloids mass production with predetermined properties and concentration.
Nanomodification of polymer packaging materials in order to add bactericide properties to them and for extension of food products shelf life.
