Antibacterial Activity Studies On Mg Doped Ceo2 Quantum Dots

Abstract

The pure and Mg doped CeO 2 quantum dots were synthesized by sol-gel technique and their properties were investigated using XRD, FTIR and HRTEM studies. The structure and size of crystallites were determined using XRD studies. The functional groups of the quantum dotswere analyzed through FTIR spectra. The selected area electron diffraction (SAED) pattern confirms the crystalline nature and cubic structure of the Mg doped CeO 2 quantum dots. Finally, the antibacterial activity of the obtained Mg:CeO 2 quantum dots was also evaluated against Gram positive bacteria staphylococcus aureus (+), Bacillus subtilis (+) and Gram negative bacteria Escherichia coli (-), Pseudomonas aeruginosa (-) using the paper disk diffusion method.
