Abstract

Enhancing the stability of nanoparticles in colloids has great potential for biological applications. Herein, stable nanoscale antibacterial materials based on silver and tantalum oxide (Ta₂O₅) were successfully synthesized by a reproducible, simple, surfactant-free, and self-templating approach termed pulsed laser ablation in liquids. The synthesized nanocomposite Ag/Ta₂O₅ was characterized using X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscopy (SEM), transmission electron microscopy (TEM), and UV–vis spectrophotometer. The Ag/Ta₂O₅ nanocomposite showed excellent dispersion stability for 90 days. Upon assessment of the newly prepared nanocomposites for their biological activity against some bacterial pathogens including Staphylococcus aureus subsp. aureus ATCCBAA-977 and Pseudomonas aeruginosa ATCC27853 using the agar plate diffusion, the results demonstrated that Ag/Ta₂O₅ nanocomposite has the highest antibacterial activity compared to the pristine Ag and Ta₂O₅ nanoparticles.
