“…Although fullerenes are not as widely characterized by CE as CNTs, several papers focused on the electrophoretic separation of fullerenes have nevertheless been published. A relatively complex electrolyte systems have been used, such as 200 mM TFA/20 mM NaOAc in MeOH/acetonitrile (10:90, v/v) , tetra‐n‐decylammonium bromide (200 mM), and tetraethylammonium bromide (40 mM) in 6% MeOH and 10% CH 3 COOH in acetonitrile/chlorobenzene (50:50 v/v) . Thus, nonaqueous capillary electrophoresis has become a rapid and useful alternative to high performance liquid chromatography for the separation of fullerenes.…”

Nanomaterials are in analytical science used for a broad range of purposes, covering the area of sample pretreatment as well as separation, detection, and identification of target molecules. This part of the review covers capillary electrophoresis (CE) of nanomaterials and focuses on the application of CE as a method for characterization used during nanomaterial synthesis and modification as well as the monitoring of their properties and interactions with other molecules. The heterogeneity of the nanomaterial family is extremely large. Depending on different definitions of the term Nanomaterial/Nanoparticle, the group may cover metal and polymeric nanoparticles, carbon nanomaterials, liposomes and even dendrimers. Moreover, these nanomaterials are usually subjected to some kind of surface modification or functionalization, which broadens the diversity even more. Not only for purposes of verification of nanomaterial synthesis and batch-to-batch quality check, but also for determination the polydispersity and for functionality characterization on the nanoparticle surface, has CE offered very beneficial capabilities. Finally, the monitoring of interactions between nanomaterials and other (bio)molecules is easily performed by some kind of capillary electromigration technique.

“…A number of applications of NACE to the determination of antidepressants, dyes, phenolic acids, parabens, alkaloids, and herbicides in environmental samples have been reported during the past two years. Worth special note in this context is the approach of Su et al to the CE separation of open-cage fullerenes, which remains a challenging task for LC. Although chemically modified cyclodextrins are still the most commonly used chiral selectors, novel compounds such as macrocyclic antibiotics have also been used for this purpose in environmental analysis in the last two years .…”

“…Among these studies, Astefanei et al [130] applied a NACE method for the analysis of C 60 in a commercial cosmetic product as an alternative to conventional LC methods. NACE has also been proposed for the separation of three open-cage fullerenes using a mixture of acetonitrile and methanol with trifluoroacetic acid and sodium acetate in order to provide the compounds with an overall positive charge via protonation [132] .…”

“…The separation of hydrophobic fullerenes by NACE has been studied by several authors [130][131][132] . Different compounds able to interact with the target analytes to form charged complexes which can migrate under the electric field are added to the background electrolyte to accomplish their separation.…”

Highlights Methodologies for fullerene aggregate characterization are discussed.  Chromatographic and electrophoretic techniques for fullerene analysis are presented.  Accurate identification and detection of fullerenes by LC-MS is critically reviewed. Graphical abstract AbstractA prominent sector of nanotechnology is occupied by a class of carbon-based nanoparticles known as fullerenes. Fullerene particle size and shape impact in how easily these particles are transported into and throughout the environment and living tissues. Currently, there is a lack of adequate methodology for their size and shape characterisation, identification and quantitative detection in environmental and biological samples. The most commonly used methods for their size measurements (aggregation, size distribution, shape, etc.), the effect of sampling and sample treatment on these characteristics and the analytical methods proposed for their determination in complex matrices are discussed in this review. For the characterisation and analysis of fullerenes in real samples, different analytical techniques including microscopy, spectroscopy, flow field-flow fractionation, electrophoresis, light scattering, liquid chromatography and mass spectrometry have been reported. The existing limitations and knowledge gaps in the use of these techniques are discussed and the necessity to hyphenate complementary ones for the accurate characterisation, identification and quantitation of these nanoparticles is highlighted.
