High revolution chemical motor with biocatalytic reaction

Abstract

A chemical motor was constructed by a catalase immobilized tube-pump and a micro turbine system was developed and demonstrated. The catalase tube-pump produced an active pressure of oxygen vapor at the tube-inside by applying hydrogen peroxide to the tube-outside as chemical energy, resulting in the oxygen gas flux. The micro bladed wheel of the artificial turbine was revolved by the oxygen flux from the tube-pump, thus the rotational velocity was correlated with the H2O2 concentration. The potential applications of the chemical motor will allow to develop some intelligent biomimetic machines.
