Description
Titanium (IV) dioxide nanoparticles are well documented to display excellent photoreactivity in the UV range; a consequence of their rather large (~3.2 eV) band gap. Recent endeavors in nanotechnology have utilized this ability as delivery agents for photodynamic therapy. This study seeks to establish a protocol for determining the rate of photoreactivity of both unmodified TiO2 nanoparticles and TiO2 nanoparticles modified for bioselectivity. Comparison will elucidate if surface modification increases or decreases photoreactivity in the UV range. To date, studies have shown a decline in the photoreactivity of modified TiO2 nanoparticles versus unmodified TiO2 nanoparticles, indicating that adding a bioselective coating may interfere with the photocatalytic activity of the oxide nanoparticles.
