Nature's most common swimmers are single-celled organisms such as microalgae that swim toward light sources, and sperm cells that swim toward an ovum. For a physicist, cells are simply biochemical machines, which must obey well-described laws of chemistry and physics. Can scientists therefore create life-like, swimming micro-machines without invoking biology?
