Original Abstract

In our study, the feasibility of QDs 2D distribution mapping on the substrate by LIBS was examined in connection with the separation possibilities; specially interaction QDs with metal cation Cu2+ and also the influence of different pH value of water soluble QDs were investigated. Results obtained from two different LIBS setups were compared and as reference method which showed the exact distribution of QDs on the substrate surface was used the fluorescence microscopy. Water-soluble cadmium QDs (Cd-QD) were prepared by formation of nanosized semiconductor particles through colloidal chemistry in so called “onepot” synthesis. CdTe capped by GSH (glutathione) and capped by MPA (3-mercaptopropionic acid). The technique described in this work allows detection of QDs injected on the selected substrate - chromatographic paper. Two commercially available table-top LIBS systems (modified UP-266 MARCO, New Wave and SciTrace, AtomTrace) were used
