Metallic Flagella


Bradley Nelson The control of metallic flagella with magnetic fields is the subject of a recent paper by Li Zhang and Bradley Nelson.[NanoLett] The synthetic approach is a top-down process, and an image of a pre-released flagellum is shown below. Although typical bacteria like E. Coli are 1-2 μm long, this system is still a …

Linear-Motor from Carbon Nanotubes


A recent paper this week by Somada et al. regarding making a linear-motor from carbon nanotubes piqued my interest.[NanoLett] The general design idea is to encapsulate a piece of carbon nanotube material within a larger carbon nanotube. If done correctly you can end up with a configuration as shown below. Reprinted with permission from American …
