Nanomotors are used throughout biology to perform tasks. Spectacular
examples include the motor protein myosin that makes muscles contract by "walking" along molecular tracks in the cell.
Professor David
Leigh's group have made the first synthetic walking molecules that move
directionally along molecular tracks. The ultimate goal of
such research is to produce artificial molecular vehicles that
can transport cargoes and perform other complex tasks at the nanoscale.
However, such 'molecular
engineering' is not easy: at the molecular level gravity is too
weak to hold the walkers onto tracks and special molecular glue,
footholds and attachment points all
have to be carefully designed to make a successful walking
molecule (see video).
