“…16,17 The quality of these dispersions are usually quantified by techniques such as absorption, fluorescence and Raman spectroscopies, 18 as well as techniques like transmission electron microscopy (TEM), scanning electron microscopy (SEM) and atomic force microscopy (AFM). 19,20 However, absorption spectroscopy in the ultraviolet-visible-near infrared (UV-Vis-NIR) range is described as the most accurate of these techniques. 21,22 Individual CNTs exhibit characteristic absorption bands in the UV-Vis-NIR region that are attributed to the van Hove singularities for unidimensional structures.…”

“…Many examples can be found of functionalized SWCNTs, such as grafting of p-methoxyphenyl [82], functionalization with adenosine monophosphate [83], covalent addition of 4-benzo-9-crown-3 ether diazonium salt [84], and many more. Noncovalent modifications are also applied [85], although these are very specific for given applications such as dispersing SWCNTs in a water matrix [86]. The use of electron-donor and -acceptor molecules is outlined by Ghosh et al [87].…”

“…Relativamente poucos trabalhos investigaram os efeitos de NTCs utilizando-se tais técnicas e novamente é possível notar a existência de resultados conflitantes. 86,[90][91][92][93][94][95][96][97] A avaliação da genotoxicidade de NTCs é assim um desafio interdisciplinar e bastante complexo, 98 …”

“…104 Em contrapartida, outros estudos mostraram que NTCs foram mais citotóxicos quando estabilizados com um surfactante. 91 O uso de surfactantes pode gerar um falso cenário de exposição, pois nem sempre estariam presentes nas situações de exposições fisiológicas.…”
