Abstract

L'invention concerne un procédé de fabrication de nanoparticules creuses. Ledit procédé consiste : a) à utiliser une quantité d'un polyélectrolyte présentant une charge, b) à utiliser une quantité d'un contre-ion présentant une valence d'au moins 2, c) à combiner le polyélectrolyte et le contre-ion dans une solution de sorte que le polyélectrolyte s'auto-assemble afin de former des agrégats sphériques, et d) à ajouter des nanoparticules dans la solution de sorte que les nanoparticules s'agencent elles-mêmes autour des agrégats sphériques. Le polyélectrolyte peut présenter une charge positive ou négative. Le taux de charge R de la charge totale des contre-ions par rapport à la charge totale du polyélectrolyte est supérieur à 1,0.
