The nanocoil’s creation inspired by bacterial flagella could give biomedical robots a boost. This novel microrobots mimics the way bacteria zip about using corkscrew-like appendages called flagella. Such propulsion could be used as part of smart drug delivery systems, which are guided through the bloodstream directly to their target. In the long term, the nanopropellers could be used to propel autonomous biomedical microrobots.

Drug delivery systems are an attractive application for this form of propulsion. By allowing drug delivery microdevices to be directed to a very precise site, therapeutics could be used more effectively.
