Abstract

A move in the right direction: Micrometersized rods with Pt/Ni/Au/Ni/Au segments move autonomously with good directionality in the presence of a magnetic field when placed in aqueous hydrogen peroxide (see picture). The propulsive force results from an interfacial tension gradient generated by the catalytic decomposition of H₂O₂ at the Pt end while the orientation stems from the interaction of the magnetic field with the magnetized Ni segments.
