制备了第一个用荧光金纳米粒子修饰的水溶性包裹二氧化钛纳米管（TNT）。在二氧化钛纳米管上生长直径约1.6 nm的金纳米颗粒，使用硫代乳酸连接剂来控制其尺寸。金团簇在水中以660纳米的波长发光，并用共聚焦显微镜对其成像。用聚l -精氨酸包裹纳米管，将金修饰的tnt悬浮在水中。
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.
