Sometimes it is useful to recycle nanoparticles that are deposited on a surface. Ultrasounds could be useful for that purpose (avoiding chemical products).
Dear Yves ,
You can use
a power density : 20 W/cm2
a frequency : 1.67 MHz
a cleaning time : 5 min
As a Solvent , you can use a dissolved gas ( oxygen, in a liquid ( water)
This can be improved by using pulsed acoustic fields
Good luck
Eric

Dear Eric,
many thanks for your valuable answer!
Any suggestion for a paper on the subject?
Best regards,
Yves.
This has to be optimised by varying the parameters:
Generally, in the laboratories ultrasound in the frequencies of 20 to 100 kHz commonly used for physical and chemical transformations.
You can use this but operating at a lower amplitude and monitoring the removal with time.
Sometimes when you apply high intensity (W/Cm2) it may remove the particles from the surface, but it may also damage the surface.
