Improved incorporation of copper nanoparticles into carbon layers
(Nanowerk News) New researches disclosed a new way to produce copper nanoparticles into the carbon layers which have wide applications in the production of CO gas and biosensors. Researchers at Sharif University of Technology, in conjunction with colleagues from Institute for Research in Fundamental Sciences, managed to find a way to produce copper nanoparticles into the carbon layers in such a way to overcome the limitations of current methods ("Study of surface plasmon resonance of Cu@Cu2O core–shell nanoparticles by Mie theory").
“Wet chemistry methods face some problems dealing with the construction of an organized array of metallic nanoparticles on the sublayer as well as keeping the sublayer clean. These drawbacks limit the application of the mentioned methods in the production of optical and electronic parts," said Tayyebe Ghodselahi, one of the researchers.
Ghodselahi added, "Today, considering their quick response and high resolution, sensors made based on the surface plasmon resonance of metallic nanoparticles have drawn the attraction of many researchers."
The special conditions of this layer deposition method including not using wet chemistry, layer deposition at room temperature, and the high controllability of copper concentration are the requirements of using these layers in the production of optical and electronic parts especially sensors. She elaborated on the applications of the copper nanoparticles used in thin carbon layers in the production of electrodes capable of carbon hydrates detection, CO gas sensors, and biosensors.
