Résumé

Nanopartículas com propriedades magnéticas podem atuar no combate oncológico por meio da hipertermia terapêutica a qual provoca a desnaturação de proteínas e, portanto, o enfraquecimento de células tumorais. A principal vantagem desta técnica é efeitos colaterais mais brandos do que os tratamentos convencionais. Objetivando uma ativação indesejada do sistema imune este trabalho propõe desenvolver uma rota para a obtenção de partículas nanométricas de poliestireno (PS) visando encapsular tais partículas. Foi utilizada uma rota livre de emulsificantes o que garantiria uma maior pureza do sistema. O material sintetizado foi analisado através microscopia eletrônica de varredura, granulometria por difração a laser, análise térmica e espectroscopia no infravermelho. Foi confirmada a obtenção de poliestireno no formato esférico com tamanho médio de partícula de 317 nm ± 58 nm adequada para o uso em sistemas biológicos
