Chemotaxis of active janus nanoparticles
WebThese active Janus particles are known as “chemical nanomotors” or self-propelling “swimmers” and have been realized with a range of catalysts, sizes, and particle geometries. Because their active translation depends on the fuel concentration, one expects that active colloidal particles should also be able to swim toward a fuel source. WebFeb 12, 2024 · The ability to engineer the behavior of highly interfacial active Janus particles near a water/oil interface by introducing motility to the system is demonstrated. Various aspects of the behavior of Janus particles near liquid/liquid interfaces have been studied through different experimental and theoretical realizations, but the effect of …
