Optofluidic microengine in a dynamic flow environment via self-induced back-action

Most existing optofluidic particle engines only operate in a static environment. Here, we present a four-energy-state optofluidic microengine that operates stably in a dynamic flow environment, a function unattainable by existing systems due to the disturbance of the fluidic drag force. This microen...
