The advancements in nanoelectronics are currently based on the two main approaches. The first is concerned with further decrease in sizes of conventional circuit elements via developments in lithography and semiconductor processing techniques. In the other approach the functional elements are being formed starting with atoms and molecules via nanoscale controlled assembly and self-organization processes. It seems that new perspective technological solutions in nanoelectronics and nanotechnology can be found on the way of building up of hybrid constructions in which advantages of both approaches are combined effectively. Clusters, nanoparticles and functional molecular nanostructures are currently considered as potential building blocks for nanotechnology and nanoelectronics circuits, and the development and introduction of new methods to control effectively its structure, composition and purposeful nanoscale organization are necessary. This presentation describes a number of new synthetic and assembling nanofabrication methods developed in our group which are based on the surface and interface interactions, effects of applied fields, biomimetic and bio-inspired strategies. The methods allow to produce organized nanostructures with unique morphologies, as nanorings, nanorods, platelike nanoparticles, complex magnetic -Fe₂O₃ ramified nanostructures, noble metal optically-active nanoparticles of different sizes with very high surface to volume ratio and core-shell structures, ordered quasi-3-D, 2-D and 1-D arrays of nanoparticles, nanoclusters and metalloproteins, planar DNA complexes. Electron transport and discrete electron tunneling effects were studied in the synthesized nanostructures.
