Bioelectrochemical Propulsion

Journal of the American Chemical Society, 2005
A carbon fiber having a terminal glucose oxidizing microanode and an O2 reducing microcathode is propelled at the water-O2 interface. The electron current in the fiber is accompanied by a flux of hydrated protons that is so fast at the solution-air interface, where the viscous drag is small, that the fiber's velocity is 1 cm s-1.

The Propulsion of Mucus by Cilia

American Review of Respiratory Disease, 1988
Abstract The presence of cilia on epithelia of the respiratory tract was reported more than 150 yr ago, and the two-layer model of mucus transport was put forward more than 50 yr ago. However, it is only in the last 10 yr or so that the motion of mucus-propelling cilia of the mammalian respiratory system has been adequately described,
