Received July 10, 2007 Abstract — Among the fields in which Russian science can chalk up, of primary importance are nanotechnologies involving nanosized-particles-based modern materials with preset properties. The specific properties of metallic nanoparticles open up wide possibilities of preparing novel materials in electronics, effective catalysts, filtering elements, biosensors, medications with high biological activity for medical, biotechnological, and agricultural applications. Physical chemistry is extremely important in the creation of interdisciplinary basic foundation of nanochemistry and applied nanotechnology of XXI century [1–4]. The methods of synthesis, in inversed micelles, of metallic nanoparticles, stable in liquid phase and in nanocomposites and showing charac-teristic bands of optical UV–vis absorption, allow using modern physicochemical methods of studying the nanostructure formation, properties, and polyfunctional activity [5–10]. The results of the studies of adsorption processes of the metal nanosized aggregates in solutions, obtained by using chromatography (high-performance liquid chromatography, thin-layer chromatography, gas chromatography) and demonstrating the important role of active surface centers and molecular interactions, may serve as a theoretical basis in producing new nanocomposite materials with unique properties [10–12].
