Abstract (en)
[origin: EP0520888A1] Nanoparticles having an extended time of capture by the reticulo-endothelial (retothelial) system. They consist of a polylactic-polyoxyethylene and/or polyoxypropylene copolymer, optionally in a mixture with a polylactic polymer.
Abstract (fr)
La présente invention concerne des nanoparticules ayant un temps de capture, par le système réticulo endothélial, allongé. Elles sont constituées d'un copolymère polylactique polyoxyde d'éthylène et/ou de propylène éventuellement en mélange avec un polymère polylactique.
