ABSTRACT
Magnetic nanoparticles offer exciting new opportunities including the improvement of the quality of magnetic resonance imaging (MRI), hyperthermic treatment for malignant cells, site-specific drug delivery and also the recent research interest of manipulating cell membranes. The biological applications of these nanomaterials require these nanoparticles to have high magnetization values, size smaller than 20 nm, narrow particle size distribution and a special surface coating for both avoiding toxicity and allowing the coupling of biomolecules. In this review, we focus on the feasibility of radionuclide labeled magnetic nanoparticles, as drug carriers, and summarize recent advances in this field.
RESUMO
Nanopartículas magnéticas oferecem novas oportunidades interessantes, incuindo a melhora da qualidade da imagem de ressonância magnética (MRI), no tratamento hipertérmico para células malignas, na administração de medicamentos sítio-específicos e também no recente interesse da manipulação de membranas celulares. As aplicações biológicas desses nanomateriais requer que essas nanopartículas tenham valores altos de magnetização, tamanho menor que 20 nm, partículas de dimensão de distribuição restrita e um revestimento especial de superfície para evitar a toxicidade e permitir o acoplamento de biomoléculas. Nessa revisão, focalizamos na viabilidade de nanopartículas magnéticas marcadas com radionuclídeos, como transportadoras de medicamentos, e resumimos os recentes avanços nesse campo.
