“…Increasingly however, concerns have been raised over potential toxicity issues with carbon nanotubes (Firme et al, 2010;Pacurari et al, 2008) and there is presently a lack of data and understanding about their impact on biological systems. Given the probable wide-spread use of CNTs in the future, it is imperative to understand their impacts on biological systems before they can be used in mainstream drug delivery.…”

“…7 Os catalisadores metálicos (usados no processo de síntese) têm sido apontados como a principal fonte dos efeitos genotóxicos, várias nanopartículas metálicas podem atuar como sítios para a geração de EROs. 6 O ataque oxidativo ao DNA tem se mostrado um dos principais efeitos que governam a genotoxicidade de amostras de NTCs contaminadas por metais. [74][75][76][77][78][79][80][81] Apesar de ser relativamente esperado que nanopartículas metálicas apresentem toxicidade, no caso dos NTCs não é possível saber se os efeitos são devidos a metais livres ou ligados ao carbono.…”

“…3,4 Nesse contexto a Nanotoxicologia desempenha um papel importante, pois investiga os efeitos dos nanodispositivos e nanoestruturas em sistemas biológicos. 5 A avaliação toxicológica de partículas e fibras em escala nanométrica 6 contribui para uma série de questões ligadas à utilização de nanomateriais em produtos comerciais. Sendo assim, o entendimento dos mecanismos de cito-e genotoxicidade de um dado nanomaterial é fundamental para a definição de seu impacto ambiental e de estratégias de proteção aos trabalhadores e consumidores.…”

“…The health effects of nano-sized particles are well-documented in various clinical and epidemiological studies. However, the toxicity has been studied using animal models such as rats, rabbits, and monkeys or tissue cultures [13][14][15][16][17] . The aim of this study was to evaluate the presence of metal-bearing particles in human tonsil tissues and amniotic fluid samples which were chosen for the potential exposure of fetuses to particles suspended in these fluids.…”
