A B S T R A C TAdvancements in nanoscience enabled the synthesis of a diverse array of engineered nanomaterials. The precise control of the composition and quality of such nanomaterials is required to ensure their eventual successful application. Also importantly, the potentially adverse environmental and/or human health effects resulting from exposure to nanoparticles (NPs) is still a critical but underexplored research area. To understand and assess the potentially harmful effects of NPs a proper knowledge of their physicochemical properties is required.Among the different available analytical tools for the characterization and quantification of engineered inorganic NPs, mass spectrometry (MS) offers outstanding capabilities. The analytical capabilities of different MS-based techniques, including elemental and molecular detection, and hybrid tools derived from their coupling with different separation approaches, to identify, characterize and quantify NPs is here revised. A forward look into trends on the use of MS for more complete chemical analysis of engineered inorganic NPs is finally attempted.

“…In recent years, nanomaterials as adsorbents for efficient separation and preconcentration of a variety of chemical species have attracted great interest due to their large specific surface area, chemical stability, corrosion resistance, high selectivity and sensitivity. Recently, we have reviewed the application of nanomaterials in analytical atomic spectrometry since 2005, including sample preconcentration, bioanalysis, chemical vapor generation (CVG), characterization and quantification analysis and other applications [33].…”

The applications of nano-surface chemistry in the field of spectral analysis have attracted growing interest in recent years. In this article, we reviewed the applications of nanomaterials-based chemical reactions for spectral analysis, including the development in plasma-catalysis, surface-enhanced spectroscopy, separation and preconcentration, chemical vapor generation, labeling and signal amplification. Introduction of nano-surface chemistry to spectral analysis not only improves the sensitivity and selectivity, broadens the application range of spectral analysis, but also affords analytical community special characterization tools.surface chemistry, nanomaterial, plasma, separation, chemical vapor generation, opticle gas sensors, atomic spectrometry Citation:Li C H, Liu R, Lü Y, et al.

In this study, a preconcentration procedure was developed for the determination of selenium in food samples using highresolution continuum source graphite furnace atomic absorption spectrometry (HR-CS GFAAS). Halloysite nanotubes (HNTs) were used as a solid sorbent in ultrasound-assisted dispersive micro solid-phase extraction (USA DMSPE) during the preconcentration step. The experimental parameters including pH of the sample solution, the amount of halloysite nanotubes, and ultrasonication time, as well as the main parameters of HR-CS GFAAS, were optimized. The limit of detection of total selenium was 0.01 μg/L and the achieved preconcentration factor was 18. The relative standard deviations (RSDs) were 6-9%. The accuracy of this method was validated by analyses of NIST SRM 1567a (wheat flour) and NIST SRM 1549 (non-fat milk powder) certified reference materials. Selenium contents measured in these reference materials were in satisfactory agreement with the certified values according to the t test for a 95% confidence level. The proposed method was successfully applied to the determination of selenium in food samples (corn flour, rice flour, oat flour, buckwheat flour, garlic, cranberries, goji berries, and raisins).
