Abstract

Abstract Translated from French L'invention concerne de nouvelles particules à base de polymère ou copolymère méthacrylique. Les nanoparticules sont de forme sensiblement sphérique, de diamètre moyen compris entre 100 et 600nm environ, de distribution homogène (système monodispersé), et comprennent au moins une unité récurrente de formule générale (I) ci-après: <IMAGE> dans laquelle R représente un atome d'hydrogène ou un groupe alkyle linéaire ou ramifié de 1 à 6 atomes de carbone, ou un group alkyle substitué par un groupe hydroxy, carboxy ou ester, comportant le cas échéant une ou plusieurs doubles liaisons éthyléniques, l'une au moins des unités récurrentes comportant au moins un groupe carboxyle et/ou hydroxyle libre. Application comme vecteur de médicament, réactif de diagnostic et produit de contraste en imagerie médicale. The invention relates to new particles based on methacrylic polymer or copolymer. The nanoparticles are of substantially spherical shape, with an average diameter of between 100 and 600 nm, of homogeneous distribution (monodispersed system), and comprise at least one recurring unit of general formula (I) below: <IMAGE> in which R represents a hydrogen atom or a linear or branched alkyl group of 1 to 6 carbon atoms, or an alkyl group substituted by a hydroxy, carboxy or ester group, optionally comprising one or more ethylenic double bonds, at least one repeating units comprising at least one free carboxyl and / or hydroxyl group. Application as a drug carrier, diagnostic reagent and contrast agent in medical imaging.
