美国德州Rice University的一班科学家不久前研制成功了一种纳米量级的“短程加速赛车”（Nanodragster），只有人头发丝宽度的五万分之一，就象是一辆改装高速车（Hot Rod），在操作或性能上可以胜过以前的任何纳米尺度的运载工具。相关论文发表在Organic Letters上：http://pubs.acs.org/doi/abs/10.1021/ol902312m

The synthesis and imaging by scanning tunneling microscopy of a mixed wheeled nanovehicle composed of a p-carborane small-wheeled short front axle and a C₆₀ large-wheeled long rear axle that has been termed a nanodragster due to the structural relation to a dragster are reported. This nanodragster is expected to exhibit motion at a lower temperature than pure C₆₀-wheeled nanocars and should allow the investigation of the role played by p-carborane wheels in directional motion.
