Abstract

Gold nanorods are widely known for their photothermal properties to treat solid tumors. Our work demonstrates the unrealized capacity to image these reagents in liquid at high resolution using Transmission Electron Microscopy (TEM). Here we perform the first atomic measurements of functionalized nanorods in solution while visualizing their dynamic behaviour with TEM.

摘要

金纳米棒因其光热性质而被广泛用于治疗实体瘤。我们的工作表明，使用透射电子显微镜（TEM）可以在液体中以高分辨率对这些试剂进行成像，这是以前未实现的。在这里，我们在溶液中进行了第一个功能化纳米棒的原子测量，同时用 TEM 可视化它们的动态行为。
