Synthesis of organized inorganic crystal assemblies

Organized crystalline assemblies of cobalt salt and gamma-iron oxide have b een produced by itt situ matrix-mediated biomimetic route. The process make s use of an organized supramolecular matrix and produces cobalt chloride cr ystals with characteristic morphology of coccolith of alga and nacreous str ucture of Pinctada martensii. Crystals of gamma-iron oxide have been produc ed with typical morphology of aragonite spherulites in regenerated shell of Pomaceae paludosa.
