Researchers have shown that they can combine a biological motor and an electric field to steer individual protein tubes along tiny channels of a glass chip.
Within living cells, a two-headed protein called kinesin acts as a biological motor, hauling cargo. Fueled by chemical energy, the protein uses the two heads to "walk" along microtubules, which form an inner scaffold in cells.
