Abstract

AGENTES DE CONTRASTE PARA ULTRASONIDOS EN LA FORMA DE MICROPLARTICULAS COMPRENDEN UNA MATRIZ BIOTOLERABLE (P.EJ. DE UN CARBOHIDRATO O UN AGENTE DE CONTRASTE DE RAYOS X) EN ASOCIACION CON UN GAS O UN PRECURSOR PARA QUE ESTAS SEAN ESTABILIZADAS PARA MEJORAR SU ESTABILIDAD Y/O ECOGENICIDAD EN VIVO, MODIFICANDO COVALENTEMENTE LA ESTRUCTURA DE LA MATRIZ, P.EJ. PARA INTRODUCIR GRUPOS ENTRECRUZADOS O PARA UNIR GRUPOS LIPOFILICOS Y/O MOLECULAS. LAS MITADES COVALENTES PUEDEN INCLUIR ENLACES BIODEGRADABLES PARA AYUDAR A LA RAPIDA ELIMINACION SUBSECUENTE DE LOS AGENTES DE CONTRASTE DEL SISTEMA.
