SYNTHESIS, STRUCTURAL CHARACTERIZATION AND ANTIBACTERIAL APPLICATIONS OF CALCIUM NANOPARTICLES

Abstract

Inorganic nanoparticles for biomedical applications have undergone extensive investigations in recent years. Among different inorganic drug carriers, calcium carbonate (CaCO3) nanoparticles show unique advantages due to their ideal biocompatibility and the potential as delivery system for loading different categories of drugs. Calcium derivatives have great potential to be applied in bone and teeth related disorders due to their ideal biocompability with the natural bone and teeth structures and the biodegradability as well. Calcium carbonate and calcium hydrogen phosphate nanoparticles are synthesized by wet chemical precipitation method. X-ray diffraction studies are made to determine the structural properties. The optical behavior of both calcium nanoparticles are studied by UV characterization. The band gaps of both the samples are also found. The antibacterial activity was tested on Gram negative and Gram positive bacterial strains.
