我们报告的第一个实时成像的个性化氮化硼纳米管（BNNTs）通过稳定与罗丹明表面活性剂和荧光显微镜。我们研究了旋转和平移扩散，并发现他们同意的基础上进行布朗运动的一个封闭的，高纵横比刚性杆的预测。我们发现，BNNTs的行为平行的个体化的碳纳米管（CNTs），表明BNNTs也可以被用作模型刚性杆来研究软物质系统，同时避免了实验的缺点，由于其强大的光吸收的CNTs。我们的技术和发现的使用和进一步发展将加速BNNT从材料工程到生物研究的应用。
We report the first real-time imaging of individualized boron nitride nanotubes (BNNTs) via stabilization with a rhodamine surfactant and fluorescence microscopy. We study the rotational and translational diffusion and find them to agree with predictions based on a confined, high-aspect-ratio rigid rod undergoing Brownian motion. We find that the behavior of BNNTs parallels that of individualized carbon nanotubes (CNTs), indicating that BNNTs could also be used as model rigid rods to study soft matter systems, while avoiding the experimental disadvantages of CNTs due to their strong light absorption. The use and further development of our technique and findings will accelerate the application of BNNTs from material engineering to biological studies.
