Green Combustion Synthesis of CeO2 and TiO2 Nanoparticles Doped with Same Oxide Materials of ZrO2: Investigation of in vitro Assay with Antibiotic Resistant Bacterium (ARB) and Anticancer Effect

Abstract

This article reports the synthesis, characteristics and biomedical applications of CeO2-ZrO2 and TiO2-ZrO2 nanoparticles. The nanoparticles are synthesized by Green combustion method. Aloe Vera, dates and pomegranate extracts are used as mediators to avoid toxicity instead of chemical reagents. Hence it is biocompatible, non-toxic and avoiding adverse effect in biomedical applications. The nanoparticles are characterized by XRD to confirm the physical structure. The FTIR, Raman and SEM with EDAX analyses the chemical composition and their morphology. The antibacterial activity of these nanoparticles is assayed by well diffusion method against the bacterial pathogens of Stephylococcusaureus, Shigillaflexneri and Bacillus sp. The anticancer effect of the nanoparticles is investigated on A549 cell line by In Vitro assay. The conceivable purpose is the hydroxyl radicals which are easily produced by oxidizing more hydroxide ions in alkaline solution. Thus the competence of the development is rationally improved at pH is 9.

Effect of calcination temperature on the properties and applications of bio extract mediated titania nano particles

“…Unquestionably, the progression of appealing nanoparticles with tuned properties is of unbelievable importance for both academic network and production 2 . Material Science evolved itself as a research hotspot in the field of nanotechnology and it is about the synthesis, characterization and study of materials in the nanometer region 3 .…”

“…Additionally, the band corresponding to TZ-SG (at 1630 cm –1 ) blue-shifted slightly as to that of TZ-ST (at 1628 cm –1 ), indicating that the interaction between surface cations and adsorbed water on the TZ-ST was strong . The peak at 1384 cm –1 belonged to the vibrational modes of the −CH group, which was attributed to the residue organics . The intensity of this band was lower for TZ-ST, which could be attributed to the fact that solvothermal treatment promotes the hydrolysis of some residual organics .…”

Synthesis of Metallic Nanoparticles Based on Green Chemistry and Their Medical Biochemical Applications: Synthesis of Metallic Nanoparticles

“…are becoming increasingly common. Developing nanoparticles as novel antibacterial agents is a new trend that may be employed in various disciplines, including biosensors, nanomedicine, and bio-luminescence technology [20]. Various microorganisms, including Klebsiella aerogenes, Bacillus subtilis, Pseudomonas stutzeri, Fusarium oxysporum, and Vericillium, have synthesized various types of metallic NPs [21].…”
