Pulsed Laser Ablation Synthesis of TiO₂ Nanoparticles and their Enhanced Antimicrobial Activity under Femtosecond Laser Irradiation

Article scientifique 2026 Autre

Résumé

This study analyzes the synthesis of titanium dioxide TiO₂-Nanoparticles (NPs), through Pulsed Laser Ablation in Liquid (PLAL). The combination was performed by irradiation of a titanium target at its second harmonic (532 nm, 10 ns pulse duration, and 10 Hz repetition rate), bv a Nd:YAG laser. The results of the analysis verified the antibacterial efficacy of the synthesized TiO₂-NPs against Methicillin-Resistant Staphylococcus Aureus (MRSA) and Pseudomonas aeruginosa, by reducing the bacterial growth, proving an effective strategy against ani-biotic resistant pathogens.
