Gas vesicles (GVs) are hollow protein nanostructures synthesized by phototrophic haloarchaea and cyanobacteria to regulate their flotation in aquatic habitats.
Bioengineered GVs have been genetically modified for diverse purposes including ultrasonic molecular imaging, gauging cellular turgor pressures, and vaccine delivery — harnessing unique acoustic, mechanical, and surface properties of GVs — but none of their current applications exploits their most fundamental characteristic: buoyancy.
