  • Title: Synthesis of gold nanoclusters: a fluorescent marker for water-soluble TiO2 nanotubes.
    Author: Ratanatawanate C, Yu J, Zhou C, Zheng J, Balkus KJ.
    Journal: Nanotechnology; 2011 Feb 11; 22(6):065601. PubMed ID: 21212487.
    Abstract:
    The first example of a water-soluble wrapped titania nanotube (TNT) decorated with fluorescent gold nanoparticles has been prepared. Gold nanoparticles ∼ 1.6 nm in diameter were grown on the TiO(2) nanotubes using a thiolactic acid linker to control the size. The gold clusters emit at 660 nm in water and were imaged using confocal microscopy. The gold decorated TNTs were suspended in water by wrapping the nanotubes with poly-L-arginine.
