| Research Abstract |
Spherical motors consisting of zinc and platinum parts formed on the surface were fabricated. The very negative redox potential of Zn2+/Zn caused spontaneous and simultaneous redox reactions on the zinc and platinum parts. As a result, a pH gradient was formed on the two sides, and the motor moved to the opposite direction with respect to generated electroosmotic flow. The motors moved in solutions of bromine, p-benzoquinone, and methanol. Furthermore, the motors could trap bacteria (E. Coli) while they were in motion.
