MALDI mass spectrometry for probing the anti- staphylococcal capability of TiO₂nanoparticles via near-UV and laser irradiation

Abstract

We report the use of MALDI-MS as an effective tool in investigating the anti-staphylococcal property of TiO2 nanoparticles under near-UV and for the first time also under laser irradiation.

Fabricating Bionic Ultraslippery Surface on Titanium Alloys with Excellent Fouling-Resistant Performance

“…Rutile TiO 2 was reported to display no bactericidal property, so the three kinds of anodic films were not toxic to bacteria and algae. 43,44 3.3. Wettability Tests.…”

“…At the same time, the size of TiO 2 nanotubes prepared at the anodizing voltage of 30 V was the largest on account of the intense peak corresponded to the more oxide, which was consistent with the results of Figure . Rutile TiO 2 was reported to display no bactericidal property, so the three kinds of anodic films were not toxic to bacteria and algae. , …”

Controllable synthesis of Ag@TiO2 heterostructures with enhanced photocatalytic activities under UV and visible excitation

“…When the Ag/TiO 2 bers are irradiated by UV-light illumination, the photo-generated electrons in the valence band of TiO 2 would transfer to the conduction band. 42,43 Then, the appropriate amount of Ag nanoparticles adhering on the surface of TiO 2 bers would capture the electrons, 44 therefore, it is benecial for the separation of photogenerated electrons and holes. The electrons captured by Ag particles would transfer to the adsorbed O 2 to generate radical species, such as cOH.…”
