Preparação de nanopartículas poliméricas a partir da polimerização de monômeros: parte I

Abstract: Resumo: Nanopartículas poliméricas produzidas a partir de polímeros sintéticos, como copolímeros do ácido metacrílico, ésteres acrílicos ou metacrílicos, têm sido amplamente utilizadas na área farmacêutica para encapsulação de princípios ativos. Essas nanopartículas apresentam as vantagens de proteção, liberação controlada, melhor biodisponibilidade e menor toxicidade, proporcionando maior conforto aos pacientes e adesão ao tratamento. A produção das nanopartículas (nanocápsulas e nanosferas) por polimerização… Show more

“…[6] Different techniques can be used to produce polymer nanoparticles loaded with biomedical compounds, including particle precipitation, liposomal preparation and miniemulsion polymerization, among others. [8] Miniemulsion polymerization is characterized by the initial preparation of a liquidliquid dispersion and the posterior polymerization of the dispersed phase, which may contain a bioactive compound, producing particles with characteristic diameters ranging from 50 to 500 nm. [9,10] Through miniemulsion polimerization, the produced latex usually presents better stability and encapsulation can be performed in situ during the reaction.…”
