Abrégé
(EN)
The present invention provides a series of biocompatible, nanoparticulate formulations that are designed to retain and deliver peptides such as anti-angiogenic factors over an extended time course. The nanoparticles can be targeted to a cell or tissue by targeting ligands crosslinked or conjugated to the corona of the nanoparticles. In addition to selective targeting, the nanoparticles also may perform noninvasive imaging using bioluminescence and/or magnetic resonance imaging via a contrast agent in the core of the nanoparticle. Also provided are methods of delivering to and, optionally, imaging of a cell or tissue. Furthermore, methods of producing the nanoparticles in batch or continous mode via simple mixing or micromiximg.

La présente invention concerne une gamme de préparations nanoparticulaires biocompatibles conçues pour retenir et administrer des peptides tels que des facteurs anti-angiogéniques pendant un laps de temps prolongé. Les nanoparticules peuvent être dirigées sur une cellule ou un tissu au moyen de ligands réticulés ou conjugués avec la couronne de la nanoparticule. A côté de leur fonction de ciblage sélectif, ces nanoparticules peuvent s'utiliser pour un imagerie non effractive au moyen de techniques de bioluminescence et/ou de résonance magnétique via un agent de contraste situé au coeur de la nanoparticule. L'invention concerne également des méthodes d'administration des nanoparticules aux cellules ou aux tissus et, éventuellement, des techniques d'imagerie appliquées à ces cellules et tissus. Sont également décrits des procédés de fabrication par lots ou en continu des nanoparticules par brassage simple ou microbrassage.
