Optically levitated nanosensors in high vacuum are excellent candidates for the detection of high-frequency gravitational waves, amongst a wider range of other potential applications. We investigate the possibility of detecting high-frequency gravitational waves with levitated opto-mechanics. The current work proposes a laser-cooled optically-levitated nano-sensor to search for a number of highly-energetic sources associated with distant cosmic events, via precision sensing of gravitational waves at micron length scale.
