Findings on Nanoparticles Described by A. De Giacomo and Colleagues (Nanoparticle Enhanced Laser Induced Breakdown Spectroscopy: Effect of nanoparticles deposited on sample surface on laser ablation and plasma emission)

By a News Reporter-Staff News Editor at Science Letter -- A new study on Nanoparticles is now available. According to news reporting out of Bari, Italy, by NewsRx editors, research stated, "In this paper the use of metallic nanoparticles (NPs) for improving Laser Induced Breakdown Spectroscopy (LIBS) is discussed. In the case of conductors an emission signal enhancement up to 1-2 orders of magnitude was obtained depositing NPs on the sample surface by drying a micro-drop of colloidal solution."

Our news journalists obtained a quote from the research, "The basic mechanisms of Nanoparticle Enhanced LIBS (NELIBS) were studied and the main causes of this significantly large enhancement were found to be related to the effect of NPs on the laser ablation process, in terms of a faster and more efficient production of seed electrons with respect to conventional LIBS. The characteristics of NELIBS-produced plasma were investigated by emission spectroscopy and spectrally resolved images. In spite of similar plasma parameters, the NELIBS plasma was found to have larger emission volume and longer persistence than the LIBS one."

According to the news editors, the research concluded: "A method to determine NP concentration and size was also proposed, which involved depositing NPs on non-interacting substrates, and proved the feasibility of LIBS as a fast detection tool fora preliminary characterization of NPs."
