METHOD FOR THE SYNTHESIS OF INERT METAL NANOPARTICLES
WO09030799
Different procedures for the synthesis and covering of inert metallic nanoparticles have been developed during the two last decades. Nevertheless, currently used methods show disadvantages, such as they consist of several steps, need high temperatures for the synthesis. From University of Valencia has been developed a new procedure for the synthesis of inert metallic nanoparticles with only one step. This method lets production of nanoparticles in a rapid way and at low temperature, controlling size, shape and concentration of nanoparticles.
Applications: The main application of the technology is in the production of inert metallic nanoparticles, for their use in the following sectors: • In cosmetics, to improve biodisponibility and features of compounds for product development (i.e. sun protection creams). • In pharmaceutics, to improve drug delivery. • In biotechnology, to trace and functionalize organic molecules and to develop biosensors, taking advantage of surface plasmon resonance (SPR) properties of metallic nanoparticles. • In petrochemical and chemical industry, as catalysers. Advantages: The most remarkable advantages provided by this technology are: • Rapidity of the metallic nanoparticle synthetic method, as it consists of only one step. • Efficiency, since size, shape and concentration of nanoparticles are controlled, as well as, their production in organic or inorganic soluble solution. • Reduced production costs, as high temperatures are required by other alternative laser ablation methods.
