One convenient way to manipulate nanoscale objects with remote controllability is actuation and propulsion by light, which is largely based on optical and photothermal-induced forces. Unfortunately, the output of optical and photothermal-induced forces is small and speed is slow. This changes with a novel and intriguing nanoactuation system: plasmonic nanodynamite. This system can be optically triggered to eject gold nanobullets with an initial speed of up to 300 m/s.
