Abstract
The invention provides a process for forming a layered nanoparticle, comprising providing a suspension comprising a core particle in a first liquid, adding a second liquid to the suspension, and adding a reagent, or a precursor for the reagent, to the suspension. The second liquid is immiscible with the first liquid. If the reagent is added to the suspension, the reagent reacts to form a layer on the core particle to form the layered nanoparticle. If a precursor for the reagent is added to the suspension, the precursor is converted to the reagent, and the reagent reacts to form a layer on the core particle to form the layered nanoparticle.
Claims9
1-34. (canceled)
A layered nanoparticle comprising an inorganic core particle or an organically modified inorganic core particle and one or more porous ceramic layers at least partially surrounding said core particle, wherein at least one region of the nanoparticle selected from the core and the one or more layers has a dopant substantially homogeneously distributed therein, said layered nanoparticle being capable of releasing the dopant.
A method for administering a drug to a patient in need thereof, said method comprising delivering to the patient a composition comprising the nanoparticulate substance according to claim 1, wherein the active substance is a drug, wherein at least one region of the nanoparticle selected from the core and the one or more layers is porous and comprises the drug substantially homogeneously distributed therein, and said nanoparticles being such that the drug is releasable therefrom.
