ONLINE COVER Optomechanical resonators are micro- or nanodevices powered and detected by optical forces. Highly sensitive, these devices detect molecular substances—such as polymers, proteins, and viruses—in vacuum, air, and liquid media. Asano et al. manufactured optomechanical probes consisting of two microbottles. They found that the device is not only capable of high molecular sensitivity in water, but also allows previously unreported free access to the target location. Further development could extend the twin-microbottle resonator’s use in viscous gel-like media and pioneer research towards ultrasensitive biochips and rheometers.
