Abstract

EL PROCEDIMIENTO SEGUN LA INVENCION SE CARACTERIZA PORQUE: (1) SE PREPARA UNA FASE LIQUIDA CONSTITUIDA ESENCIALMENTE POR UNA DISOLUCION DE LA PROTEINA Y, EVENTUALMENTE, DE UNA SUSTANCIA BIOLOGICAMENTE ACTIVA EN AGUA O EN UNA MEZCLA ACUOSA A UNA TEMPERATURA INFERIOR A LA DE COAGULACION DE LA PROTEINA, Y PUDIENDO AÑADIRLE UNO O VARIOS TENSIOACTIVOS, (2) SE PREPARA UNA SEGUNDA FASE LIQUIDA CONSTITUIDA ESENCIALMENTE POR AGUA O UNA MEZCLA ACUOSA A UNA TEMPERATURA SUPERIOR A LA DE COAGULACION DE LA PROTEINA, PUDIENDO CONTENER UNA SUSTANCIA BIOLOGICAMENTE ACTIVA, Y PUDIENDO AÑADIRLE UNO O VARIOS TENSIOACTIVOS, (3) SE AÑADE, CON AGITACION MODERADA, UNA DE LAS FASES LIQUIDAS OBTENIDA EN (1) O (2) A LA OTRA EN CONDICONES DE PH ALEJADO DEL PUNTO ISOELECTRICO DE LA PROTEINA, DE MANERA QUE SE OBTIENE DE MODO PRACTICAMENTE INSTANTANEO UNA SUSPENSION COLOIDAL DE NANOPARTICULAS DE LA PROTEINA Y, EVENTUALMENTE, DE LA SUSTANCIA BIOLOGICAMENTE ACTIVA, Y (4), SI SE DESEA, SE ELIMINA TODA O PARTE DEL AGUA ODE LA MEZCLA ACUOSA, PARA OBTENER UNA SUSPENSION COLOIDAL DE CONCENTRACION DESEADA EN NANOPARTICULAS O PARA OBTENER UN POLVO DE NANOPARTICULAS. APLICACIONES: BIOQUIMICA, FARMACIA MEDICINA, COSMETICA.
