Abstract

"PROCESSO PARA PREPARAçãO E USO DAS MICROESFERAS BIODEGRADáVEIS MONODISPERSAS E MICROESFERAS BIODEGRADáVEIS MONODISPERSAS" A presente invenção refere-se a um processo para a preparação de microesferas biodegradáveis monodispersas que compreendem as etapas de: (a) preparação de uma emulsão que compreende pelo menos uma fase polimérica e pelo menos uma fase aquosa, sendo que a razão das viscosidades entre a fase polimérica dispersa e a fase aquosa contínua está compreendida entre 0,1 e 10; (b) submissão da emulsão obtida a um cisalhamento laminar controlado; (c) eliminação do solvente da fase polimérica; e (d) isolamento das microesferas assim obtidas. A presente invenção refere-se também ao uso das microesferas assim preparadas.
