Summary of the technology
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.
Description of the tech for sale
Different procedures for the synthesis and covering of inert metallic nanoparticles have been developed during the two last decades, like suspension of metallic and silicon nanoparticles, synthesis by organic solvent addition or several laser ablation methods. Nevertheless, currently used methods show disadvantages, such as they consist of several steps, need high temperatures (500-1000 ºC) for the synthesis, etc. Thus, an increase of production costs is caused. Researchers from University of Valencia have developed a new procedure for the synthesis of inert metallic nanoparticles with only one step.
Specifications
Method for obtaining stable colloid of inert metal nanoparticles in a single step comprising the laser ablation of a solid target submerged in a liquid medium containing metal salts. The nanoparticles synthesised using the aforementioned method have a controlled morphology and size and a high SPR absorbance intensity in a narrow wavelength range. This method lets production of nanoparticles in a rapid way and at low temperature, controlling size, shape and concentration of nanoparticles.
Main advantages of its use
- See “New and innovative aspects” section
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.

Light-Emitting Electrochemical Cells based on ionic dyesThe use of ionic dyes leads to materials that do not suffer from compatibility issues and allows for a much more economic production of LECs. These dyes are known for many years and used in applications such as photographic films and recordable DVD discs, and are produced in large quantities at low cost. Some examples of suitable ionic organic dyes are cyanine, hemicyanine and squarilene dyes.
