Determination of Inorganic Arsenic in Samples of Marine Origin
Marschner, Karel; Matoušek, Tomáš; Dědina, Jiří; Musil, Stanislav
2017 - English
A fast screening method for determination of inorganic arsenic in marine samples was developed. This method is based on selective\nhydride generationanddetectionby inductively coupled plasmamass spectrometry. Using a high concentration of hydrochloric acid\ntogether with hydrogen peroxide for hydride generation leads to selective conversion of inorganic arsenic species into arsane. The\naccuracy of this method was verified by comparative analyse by high performance liquid chromatography coupled with hydride generationandatomic\nfluorescence detection. Keywords: arsenic speciation; inorganic arsenic; hydride generation Available on request at various institutes of the ASCR

Fate of smelter dusts in temperate and semi-arid soils
Ettler, V.; Jarošíková, A.; Mihaljevič, M.; Kříbek, B.; Veselovský, F.; Penížek, V.; Vaněk, A.; Šráček, O.; Matoušek, Tomáš; Mapani, B.; Kamona, F.; Nyambe, I.
2017 - English
Our results indicate that, compared to semi-arid areas (where inorganic contaminants are rather immobile in soils despite their high concentrations), a higher potential risk exists in smelter-affected humid areas, where metal(loid) contaminants can be easily released by extensive weathering of particulates in the soil systems. Keywords: soils; smelter dusts Available in digital repository of the ASCR

Characterization of upconversion nanoparticles by fluorescence spectrometry and capillary electrophoresis
Vaněčková, T.; Zítka, J.; Hlaváček, Antonín; Adam, V.; Vaculovičová, M.
2017 - English
Upconversion nanoparticles (UCNPs) are a novel class of luminescent tags for applications in life and material sciences. Unlike traditional fluorophores, UCNPs exhibit emission of shorter wavelength under near-infrared excitation (typically 980 nm). In this work, we have examined these unique photophysical properties by fluorescence spectrometry and capillary electrophoresis. UCNPs co-doped with Yb(III) and Er(III) were characterized using laboratory-made fluorescence spectrometer. We have exploited and evaluated two excitation sources and the dependence of the fluorescence of UCNPs on the relative excitation power. Moreover, capillary electrophoresis with laser-induced fluorescence (CE-LIF) detection was for the first time used for characterization of the nanoparticles. It was proved that CE-LIF is a valuable method to be used for investigation of upconversion luminiscence and monitoring of the interactions of UCNPs with other molecules of interest. Keywords: capillary electrophoresis; fluorescence spectrometry; upconversion nanoparticles Fulltext is available at external website.

Development of microfluidic device for droplet generation and microparticle encapsulation
Křivánková, Jana; Foret, František
2016 - English
Microfluidic devices combined with various bioanalytical and optical sensors proved\ntheir potential in chemical, biological, and biomedicine applications. At a droplet\nmicrofluidic device a fluid is divided into numerous droplets surrounded by a\ncontinuous immiscible fluid phase. Generated droplets serve then as\nvessels/microcapsules for delivering drugs, nutrients as well as for encapsulating of\nbiologically active particles and cells.\nDescribed experimental study deals with the development of a practical dropletbased\nmicrofluidic chip useful for production of monodisperse water/oil emulsion and\nfor encapsulation of thin-metal magnetic microsheets. Keywords: microfluidic device; microparticle encapsulation Available in digital repository of the ASCR
