Summary of the technology
This new procedure (not described in the bibliography) allows the manufacture of monolayers of metal nanoparticles linked by molecules of organic compounds. As you can see in Specifications, this procedure consists in two successive processes. One of the main advantages of this technology is the minimization of impurities in the functionalized monolayer compared to commonly used techniques. Besides, the manufacture of Schotty diode with this new procedure has been shown for the first time. In the same line, this procedure allows the use of monolayers of metal nanoparticles for metabolite detection. These are two unique and differents aspects of this technology in relation to other known used techniques.
Description of the technology
The Research group in Microsystems and Nanotechnologies for Chemical Analysis of the Department of Electronic, Electric and Automatic Engineering of School of Engineering (ETSE) of Rovira i Virgili University have developed a new procedure for manufacturing monolayers of metal nanoparticles linked by molecules of organic compounds.
This new procedure consists of two successive processes: 1. - A first step where a deposition of metal nanoparticles dispersed on a base substrate is performed. This phase is carried out by thermal evaporation techniques or physical vapour deposition. A piece of pure metal as a precursor is used. 2. - A second step that consists in a functionalization of the metal nanoparticles with organic compounds. These organic compounds act as a linker. This phase is carried out with coating techniques. A solution of the linker organic compound in a fast evaporating organic solvent is used. This organic solvent do not react with the linker organic compound.
Main advantages of its use
- •The technology is a new procedure for obtaining functionalized monolayers of nanoparticles. This procedure is not described in the bibliography. •This procedure allows manufacture monolayers of metal nanoparticles with different practical applications. •Maximum minimization of impurities in the functionalized monolayer compared to commonly used techniques. •For the first time, the manufacture of Schotty diode with this new procedure has been shown. •Use, for the first time, of monolayers of metal nanoparticles for metabolite detection.
- This technology could be applied in obtaining chemical sensors for detecting vapors, in the manufacture of diodes, in the manufacture of transistors and in the manufacture of substrates for Laser Desorption Ionisation Mass Spectrometry (MALDI, SALDI), for detecting metabolites. The market for this technology would be the chemical and biochemical industry (chemical sensors, detection of metabolites, etc.) and the electronics industry.
