Abstract

The field of the present invention relates to the stabilisation of nanoparticles in aqueous dispersion and, in particular, the stabilisation of nanoparticles by encapsulating the nanoparticles in a micellular combination. The field of the present invention further relates to a micellular combination of nanoparticles and a method of manufacture of the micellular combination and uses thereof. In a first aspect the present disclosure teaches a micellular combination that allows the stable dispersion of nanoparticles into aqueous environment. The micellular combination comprises at least one nanoparticle in a core of the micellular combination. A plurality of surfactants is co-assembled with a plurality of hydrophobic ligands on the surface of the nanoparticle in such a way that the hydrophilic part of the surfactant forms a hydrophilic shell around the core of the micellular combination.
