I don‘t know about nanobubbles, but microbubbles are used in contrast enhanced ultrasound. Basically overcoming the resolution limit of conventional ultrasound systems to create an image of your microvessels for medical diagnostics.

That's interesting. Why aren't they deleterious to the ultrasound resolution due to the constant refraction from the medium shift? Does that refraction change act like dithering in astronomical images?
