Stephen J. Ebbens Jonathan Howse The current state of the art in nanopropulsion devices was recently reviewed by Ebbens and Howse in an article last Friday.[SoftMatter] A short summary of the nano- systems is presented below with video action shots when I could find them. The Whitesides Catalyst: Pt Fuel: H2O2 Propulsion: Bubble propulsion Terrain: Aqueous meniscus Max Speed: 2 cm/s Mitch’s Name: The Karl Benz (since it was the first) Article: Autonomous Movement and Self-Assembly The Sen-Mallouk-Crespi Catalyst: Pt Fuel: H2O2 Propulsion: Self electrophoresis/Interfacial tension Terrain: Settled near boundary in aqueous solution Max Speed: 6.6 um/s Mitch’s Names: The Ford Mustang of nanopropulsion. (It is a hot rod, get it?) Article: Catalytic Nanomotors: Autonomous Movement of Striped Nanorods The Jones-Golestanian Catalyst: Pt Fuel: H2O2 Propulsion: Pure self diffusiophoresis Terrain: Free aqueous solution Max Speed: 3um/s Mitch’s Name: The Volkswagen Beetle Article: Self-Motile Colloidal Particles: From Directed Propulsion to Random Walk The Mano-Heller Catalyst: Glucose oxidase and Biliruben oxidase Fuel: Glucose Propulsion: Self electrophoresis Terrain: Aqueous meniscus Max Speed: 1 cm/s Mitch’s Name: The Komatsu Truck (because it is huge) Article: Bioelectrochemical Propulsion The Feringa Catalyst: Synthetic catalse Fuel: H2O2 Propulsion: Bubble/interfacial Terrain: Acetonitrile solution Max Speed: 35 um/s Mitch’s...
