The first part of lecture is aimed at technologies for preparation of nanostructures using "top-down" and "bottom-up" approaches and characterization of nanostructures using scanning probe microscopy. Next part is devoted to formed nanomaterials and their unique properties with respect to nanoparticles, fullerenes, nanotubes, nanocomposites, and next organic or inorganic nanostructured materials. Part of the lecture about nanobiology will introduce biomimetic nanostructures and biomolecular motors. Micro- and nano-electromechanic systems together with nanosystems for electronics and optoelectronics are next examples of wide application potential of nanotechnologies.
