The present invention relates to a nanoparticle comprising self- assembled crosslinked, amphiphilic block copolymers and at least one immobilized dye, wherein the sell-assembled, crosslinked, amphiphilic block copolymers comprise a hydrophilic block and a hydrophobic block, wherein the self-assembled, crosslinked, amphiphilic block copolymers are self-assembled to form a core of the nanoparticle comprising a hydrophobic block, wherein the hydrophobic block is derived from at least one pendant multifunctional crosslinked alkoxy silane or amino silane moiety, and an exterior of the nanoparticle comprising a hydrophilic block, and wherein the immobilized dye is immobilized in the core
L'invention concerne une nanoparticule comprenant des copolymères séquencés amphiphiles réticulés auto-assemblés et au moins un colorant immobilisé, lesdits copolymères séquencés comprenant un bloc hydrophile et un bloc hydrophobe. Ces copolymères sont auto-assemblés de sorte que le cAEur de la nanoparticule comprend un bloc hydrophobe, ce bloc hydrophobe étant obtenu à partir d'au moins une fraction alcoxy silane ou amino silane réticulée multifonctionnelle latérale, et l'extérieur de la nanoparticule comprenant un bloc hydrophile, le colorant immobilisé étant immobilisé dans le cAEur.
