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.


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


  • 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.
