Any idea if the key to this is preferential uptake of vesicles by cancers or some way to 'aim' what the abstract calls "ultrasound-induced inertial cavitation", or, given the way resonance works, if it's just a matter of targeting the vesicles by size - and cancers show a preferential uptake of vesicles of a particular size? Or are the vesicles distributed throughout the body and the key is using the interference pattern between two frequencies to produce the resonant frequency to localize the effect?

I'm curious, but not quite curious enough to buy access...

Thanks for bringing this one up!

Oh, and yeah, the boundary between (nano)mechanical and biochemical is very grey.

(e.g. the rotary ADP->ATP mechanism in our mitochondria)
