Nanobots: Delayed ignition and propulsion of catalytic microrockets

The delayed ignition and propulsion of catalytic tubular microrockets based on fuel-induced chemical dealloying of an inner alloy layer is demonstrated.The versatile “blastoff” control of these chemical microrockets holds considerable promise for designing self-regulated chemically-powered nanomachines with a “built-in” activation mechanism for diverse tasks.
