Combination of Paraconiothyrium brasiliense fabricated titanium dioxide nanoparticle and antibiotics enhanced antibacterial and antibiofilm properties: A toxicity evaluation

Surface modification of TiO2 nanoparticles with organic molecules and their biological applications

“…Sathiyaseelan et al synthesized modified TiO 2 NPs using an aqueous extract of the endophytic fungus Paraconiothyrium brasiliense (Pb) to improve the antibacterial activity of common standard antibiotics at a minimum concentration. 208 The modification of TiO 2 NPs with the Pb fungus significantly enhanced the antimicrobial and antioxidant properties, biocompatibility, and stability of the TiO 2 NPs. The authors used these modified TiO 2 NPs with standard antibiotics (erythromycin, ampicillin, gentamicin, vancomycin, and tetracycline) to improve the antibacterial properties of these antibiotics without significant adverse effects.…”

Enhancing the Antioxidant, Antibacterial, and Wound Healing Effects of Melaleuca alternifolia Oil by Microencapsulating It in Chitosan-Sodium Alginate Microspheres

“…Moreover, the bacterial growth curve with each sample and without the sample was evaluated by the broth dilution method according to the earlier protocol [ 28 ]. Further, bacterial cell viability and the effect of treatment were studied through SYTO 9/PI fluorescent bacterial live and dead assay [ 29 ]. In brief, both Gram-positive ( S. aureus ) and Gram-negative ( E. coli ) bacterial pathogens were incubated with each sample for 12 h. After incubation, the bacteria were collected by centrifugation and washed with PBS twice.…”

Sol–Gel-Derived TiO2 and TiO2/Cu Nanoparticles: Synthesis, Characterization, and Antibacterial Efficacy

“…Among these MO nanoparticles, TiO 2 is the most explored nanomaterial due to its excellent physicochemical, mechanical stability, earth abundance, and antibacterial properties. ,− Furthermore, TiO 2 turned out to have strong capabilities as an adsorbent material for the removal of heavy metal ions in water. , In addition, the antibacterial effect of these TiO 2 nanoparticles is attributed to reactive oxygen species (ROS) mediated membrane degradation. ,, The nanoparticles can react with O 2 and −OH functional groups attached to the surface to produce free radicals. As a result, the enhanced surface area and small size can improve the antibacterial effect as the nanoparticles can easily pass through the membrane and kill the bacteria .…”
