Antibacterial Applications of Un-doped and Doped CdO Nanocrystalline Thin Films
J. Environ. Nanotechnol., Volume 8, No 2 (2019) pp. 01-09
Abstract
Nanocrystalline thin films of un-doped and Al-doped cadmium oxide were synthesized using the Chemical bath deposition method and were annealed at 500 ˚C. The films were characterized to study their structural, optical and compositional properties. Antibacterial activity of CdO films was assayed by using Agar well-diffusion technique. The antibacterial activity of un-doped and Al-doped CdO solutions was analyzed using the gram-positive bacterium, Bacillus cereus and the gram-negative bacterium, Vibrio cholera. The present study has revealed that the diameter of the zone of inhibition is found to be more for gram-negative bacteria than gram-positive for both un-doped CdO and Al-doped CdO.
