“…According to the literature, since nanofibers are not retained by the most used plankton net, they are partially included in NPs count, despite fiber are prevalent than particulate [114]. According to Abdolahpur Monikh et al [119] micro(nano)plastics and POPs tend to accumulate in lipid tissues. For this reason, eggs shells represent an excellent way to monitor the bio-accumulation in females of a species [119].…”

Searching Nanoplastics: From Sampling to Sample Processing

Nanoplastics (NPs) are considered emerging pollutants, namely unregulated contaminants whose toxic effect on humans and the environment has been demonstrated or suspected. They are the result of the physical fragmentation of the plastics that over time reach smaller dimensions (<100 nm). The issues related to the characterization and quantification of NPs in the environmental matrices are mainly related to the infinitesimal size, to the fact that they are found in bulk, and to the different physico-chemical forms in which the same polymer can evolve over time by degradation. To deal with the study of a new class of pollutants it is necessary to assess the entire analytical method, carefully considering every single step (sampling, cleanup, qualitative, and quantitative analysis) starting from the validation method in the laboratory. This paper reviews the analytical method steps, focusing on the first ones, which the current literature often underestimates: laboratory tests, sampling, and sample processing; in fact, most errors and the quality of the analyses often depend on them. In addition, all newly introduced sample processing methods were examined.

“…Analytical science has benefited notably from the incorporation of nanostructured materials as tools but also have contributed for the development of new methodologies to control their synthesis and facilitate their characterization [1,3,4]. In this concern, various nanoparticles are considered as new kind of analytes and several analytical methods have been proposed as alternative for obtaining both chemical (composition and mass concentration) and physical (e.g., shape, size, and stability) information [5–7]. In the last years, CE has demonstrated to be useful for characterization of nanomaterials, especially with regard to the size, surface, and interaction properties [8].…”

Capillary electrophoresis coupled to chemometrics for analysis of carbon dots in nanoparticles mixtures

et al. 2022

Since their discovery in 2004, carbon dots (CDs) have attracted attention due to their intrinsic physicochemical properties and the easy synthesis from simple precursors. However, quantification of CDs in mixtures of nanoparticles with similar sizes and surface functionality is still a challenging issue for research applications or regulatory purposes. In this work, CDs and silver nanoparticles were first synthesized under alkaline conditions by using glucose as precursor and capping agent, respectively. Mixtures of these nanoparticles were made at micromolar range, without purification, and then analyzed by CE-DAD, using an electrolyte solution composed of 20 mM sodium borate and 20 mM SDS at pH 8.5, in a total time of <15 min. The three-way electrophoretic data were then decomposed by advanced chemometric models, parallel factor analysis and multivariate curve resolutionalternating least-squares. The explained variances for both models were 95.8% (parallel factor analysis) and 85.3% (multivariate curve resolution-alternating least-squares). In both cases, the quality of the results was verified by the root mean square standard deviation coefficient variation, which resulted lower than 5%, and no significant bias was observed at 95% of statistical confidence. Satisfactory prediction for CDs concentration was obtained with recovery values between 80.0% and 115%.

“…Given our lack of understanding of the potential health impacts of CNT ingestion, it would be useful to determine how CNTs behave in natural systems and how they can be quantified. Carbon nanotubes have been analyzed in environmental media using several techniques, such as Raman spectroscopy, infrared analysis, microwave induced heating, isotope labeling, and electron microscopy (Das, Bancroft, et al, 2018;Das, You, et al, 2018;Das et al, 2019;Dong, Xia, Yang, Lin, & Mao, 2018;Monikh et al, 2019;Petersen et al, 2016). For instance, near-infrared fluorescence microscopy was used to analyze CNTs in phagocytic cells cultured with CNTs suspension in vitro (Cherukuri, Bachilo, Litovsky, & Weisman, 2004).…”

Quantification of carboxyl‐functionalized multiwall carbon nanotubes in plant tissues with programmed thermal analysis

et al. 2021

In this study, carboxyl functionalized multiwall carbon nanotubes (c‐MWCNTs) in plant (lettuce [Lactuca sativa Bionda Ricciolina]) tissues were quantitatively analyzed with programmed thermal analysis coupled with a sequential digestion. Programmed thermal analysis evidenced a linear relationship between c‐MWCNT–bound C and elemental C detected. A detection limit of 114–708 μg C g−1 plant tissues (dry mass) was achieved for analysis of c‐MWCNTs. The method was demonstrated using the tissues of lettuce cultured hydroponically for 3 wk with c‐MWCNTs at an exposure of 10 and 20 μg ml−1. This quantitative analysis can be used to provide insights into carbon nanotube exposure through agricultural products and promote its sustainable application.
