The studied materials can be used as superhydrophobic coatings, high-temperature sensors, and in antistatic packaging. The chemical reduction approach towards the production of stable non-spherical silver nanoparticles using sodium tetrahydroborate in the presence of sodium citrate as a stabilizer exhibiting the surface plasmon resonance absorption in the long-wave spectral range (400-950 nm) is developed. Analysis of optical absorption spectra and TEM data allows to observe the changes in the morphology of Ag nanoparticles in the colloidal system, to find out the optimal synthesis conditions for the creation of their long-term stabile materials. These characteristics suggest their use together with the magnetic carriers as targeted medical delivery materials. The one-stage, simple, low energy consuming method for synthesis of the semiconductor composite films based on Ce2Ti2O7 is developed. The obtained composites can be used as stable, long stable semiconductive coatings for electronic devices, as well as components for the filters of sunlight and/or visible light blocking at certain wavelength range. The control of heavy metal ions release, in particular copper and iron, into an aqueous environment from heterogeneous nanosystems by a fluorescent method using biocompatible organic molecules (under the influence of UV and visible light) is proposed as clinical and environmental monitoring. The titanium dioxide modified with tungsten, copper and silver ions films covered on a glass or metal plate were synthesized via template sol-gel method. The obtained films show high corrosion resistance. The used method of substrate cover allows producing coating on arbitrary shape therefore, the obtained films can be used as corrosion-resistant bactericidal surfaces.
