Encapsulation and sustained release of curcumin using superparamagnetic silica reservoirs

Chemistry. 2009 Jun 2;15(23):5661-5. doi: 10.1002/chem.200802747.


For controlled release and targeted delivery of curcumin in an aqueous medium a method of encapsulating curcumin and magnetic nanoparticles inside porous silica matrix has been developed. Curcumin and superparamagnetic nanoparticles are loaded inside porous silica in a single process. The graphic shows the TEM image of microtomed sample of Fe(3)O(4) particles surrounded by a silica matrix.
