Nanoparticle Enhanced Laser Induced Breakdown Spectroscopy (NELIBS) as a technique for elemental analysis of microdrops at sub ppm level

Original language description

Nanoparticle Enhanced Laser-Induced Breakdown Spectroscopy (NELIBS) is recently used modification of LIBS technique, where the use of nanoparticles decreases Limits Of Detection (LOD) or even in some particular cases enables the detection of minor elements not detectable with conventional LIBS. In the previous studies NELIBS applications have been presented on different kinds of samples such as metals, transparent samples, fresh samples and liquids. As it is well-known, solutions can be successfully analysed with LIBS either directly in the liquid phase, e.g. by Double Pulse (DP) techniques or by depositing and drying drops of solution on a substrate. While DP-LIBS enables analysis of solutions down to ppm levels, the method of drying several drops of solution virtually does not have any LOD limitation, as far as there is no restriction in the available amount of solution. On the contrary, if only few microliters of solution are available for the analysis, sensitivity can become a major issue in LIBS analyses. In these cases, the use of NPs can strongly improve the LIBS sensitivity. In the present work, the use of NELIBS as a tool for the elemental chemical analysis of microdrops of solutions with analyte concentration at sub-ppm level has been investigated in different liquid environment in order to check the analytical capabilities of NELIBS in aqueous, organic and biological solution. The results reveal some important characteristics of the plasmon enhanced ablation and of the emission intensity enhancement during NELIBS. In the frame of this observations, new interesting applications, such as the quantification of metals in protein systems and the elemental analysis for forensic purposes will be discussed.
