Toxicologia de nanomateriais

Authors: Martins, Luís Miguel Ferraz;

Toxicologia de nanomateriais

Abstract

A Nanotecnologia é uma ciência multidisciplinar que consiste na otimização das propriedades da matéria permitindo o desenvolvimento de sistemas com um tamanho na escala dos nanómetros. As nanopartículas são partículas cujas dimensões estão entre 1 e 100 nanómetros, podem ser produzidas naturalmente pela natureza ou desenvolvidas pelo homem, e podem ser incorporadas em diferentes processos industriais, o que leva a uma grande exposição ao nível ambiental. Apresentam propriedades específicas relativamente à sua escala nanométrica, propriedades essas que variam quanto ao tamanho, composição química, forma e superfície. Existem diversas áreas onde as nanopartículas podem ser aplicadas, tanto na área alimentar, à eletrónica, indústria farmacêutica, cosmética, biotecnologia, médico-hospitalar e agrícola. A Nanomedicina é uma área em franca expansão e o recurso às nanotecnologias disponíveis, revela-se promissor no que respeita ao desenvolvimento de terapias convencionais. Neste trabalho o principal objetivo é estudar e caraterizar os possíveis efeitos tóxicos das nanoparticulas tanto nos seres humanos como no ambiente.
