Registration Date 19-02-2015 Organization Institute of Surface Chemistry of the National Academy of Sciences of Ukraine popup.description2 The techniques of directed synthesis of nanoscale composites of gold, silver and copper with a controlled morphology, a size and optical properties to solutions and suspensions of silica. Such techniques have several advantages because they are simple, fast and energy efficient and allow to receive stable nanomaterials with a wide range of structural and functional properties. In particular, nanoparticles of colloidal silver and heterogeneous composite Ag / SiO2 exhibit high antimicrobial activity against a number of microorganisms (Escherichia coli, Staphylococcus aureus, Candida albicans) and maintain the stability and properties of two years or more. Bimetallic nanoparticles Ag / Au with tryptophan when used as anticancer drugs can reduce the hepato- and nephrotoxicity of nanoscale metals. A phenomenon of amplification of signals in the presence of tryptophan gold nanoparticles in the fluorescence spectra and Raman scattering can be the basis for the creation of highly sensitive biomarkers. Such antimicrobial materials and highly effective antitumor agents with toxicity can be prepared in the form of solutions, suspensions, powders, and the tissue that will enable their use in various environments and systems.
