Synthesis of organized inorganic crystal assemblies

Organized crystalline assemblies of cobalt salt and g-iron oxide have been produced by in situ matrixmediated biomimetic route. The process makes use of an organized supramolecular matrix and produces cobalt chloride crystals with characteristic morphology of coccolith of alga and nacreous structure of Pinctada martensii. Crystals of g-iron oxide have been produced with typical morphology of aragonite spherulites in regenerated shell of Pomaceae paludosa.
