What is nanotechnology? As a recent studies shows, there is little consensus on what exactly nanotechnology is. The several existing definitions illustrate the heterogeneous nature of nanotechnology. The US National Nanotechnology Initiative project define nanotechnology as technology concerned with materials and systems whose structures and components exhibit novel and significantly improved physical, chemical and biological properties, phenomena and processes because of their small nanoscale size. Structural features in the range of about 10-9 to 10-7 m (1 to 100 nanometers) determine important changes as compared to the behavior of isolated molecules (1 nanometer) or of bulk materials. The European Commission working group on mapping of excellence in nanotechnology developed the working definition of nanotechnology - the manipulation, precision placement, measurement, modelling or manufacture of sub-100 nanometer scale matter. The great variation in expert opinions is due to the nature of this emerging area as a potential area that integrates so far separate, autonomous and to some extent unrelated disciplines. The term nanotechnology appeared on the scientific scene for the first time in the early 1970s. Taniguchi introduced it in 1974 to describe ultra-fine machining, or more specifically the precision manufacture of mechanical parts with finishes and tolerances in the nanometer range. Eric Drexler, the director of Foresight Institute, promoted the idea of self-assembling systems of molecules that could act as molecular machines. In the course of the past decade, the term nanotechnology has been broadened well beyond the original meaning, which limited it to the areas of physics and precision engineering. It includes now a variety of other topics. For instance, it is applied to "almost any materials or devices which are structured on the nanometre scale in order to perform functions or obtain characteristics which could not otherwise be achieved". Formulating an appropriate search strategy for the mapping exercise depends critically on how the area that is to be mapped is defined. Typically, emerging fields are characterized by a multiplicity of definitions, none of which is generally recognized. To avoid the manipulation of nanotechnology meaning by traditional research groups with intention to get funding from the new funding sources, it is important to develop the methodology for mapping the competence in the field. The overview of research in nanotechnology in Lithuania was based on the methodology developed by the European Commission working group on mapping of excellence in nanotechnology. This talk presents the methodology and results of the study in the area of nanotechnology in Lithuania, consisting in bibliometric exploration and patents analyses that aimed to prepare the mapping of excellence in that area. The additional source of information which was taken into account was the participation of Lithuanian research groups in the submitted proposals "Expression of interest" and "Integrated projects" to European Commission in 2002. The findings of mapping the competence have shown that the nanotechnology instrumentation, emerging nanobiotechnology represent the main research activity areas in Lithuania, with some research in nanomaterials field.
