Carbonate microparticles for hollow polyelectrolyte capsules fabrication

Calcium, cadmium and manganese carbonate crystals were used as core material for fabrication of hollow polyelectrolyte capsules by means of the Layer-by-Layer assembly. The use of inorganic templates is a way of fabrication of clean capsules, which is essential for basic research and is a significant step towards their biocompatibility. The ways of particle and capsule fabrication and characterization are described. Scanning electron microscopy (SEM)-Energy dispersive X-ray spectroscopy (EDX) measurements proved the purity of the hollow capsules from the core material. The capsules obtained were characterized by scanning force microscopy, and confocal fluorescence microscopy.
