Precipitated calcium carbonate nano-microparticles: applications in drug delivery

Calcium carbonate CaCO precipitated particles present huge applications in drug delivery systems because their characteristics such as size distribution crystalline phase and specific surface area can be precisely tailored during the synthesis Besides this most of the processing methods present competitive costs and produce highly biocompatible materials This work reviewed briefly some of the many chemical and biological synthesis methods for CaCO nano microparticles as well as their combination with different macromolecules active principles polyelectrolytes and DNA
