808 nm light triggered black TiO2 nanoparticles for killing of bladder cancer cells

Hydrothermal synthesis and characterization of nanostructured titanium monoxide films

“…4b) can be decomposed into two components centered at 459.6 and 458.5 eV, attributable to different oxidation states of titanium. [42][43][44][45] The main component at 458.5 eV corresponds to the Ti 4+ state. [43][44][45] The second component at 459.6 eV probably is due to the small or Ti-OH contribution.…”

Nano Titanium Dioxide -An Effective Photocatalyst for Emerging Applications

“…With that, the black TiO 2 nanoparticle synthesized through a facile calcination method combined with an in situ controllable solid state reaction approach shows narrow bandgap of ~2.32 eV which enhance the photo response to visible light and near infrared region. At 808 nm, more reactive oxygen species were induced to provide phototherapy to kill the bladder cancer cells [44]. In the case of site specific drug delivery, TiO 2 has been employed to increase the effectiveness of the drugs.…”

Controllable Synthesis of Inverse Opal TiO2‐x Photonic Crystals and Their Photoelectric Properties

“…Ni et al. have synthesized TiO 2‐ x by reducing TiO 2 with NaBH 4 . These new methods are much safer, but some of them are neither highly controllable nor energy‐efficient, since some of them require a relatively high temperature.…”

“…[11] Ni et al have synthesized TiO 2-x by reducing TiO 2 with NaBH 4 . [12] These new methods are much safer,b ut some of them are neither highly controllable nor energy-efficient, since some of them requirea relativelyh igh temperature. Therefore it'se ssential to develop safer,s impler and more controllable ways to synthesize TiO 2-x more effectivelywith cheap raw materials.…”
