what i experiance is,,magnetic metal particles can gather at one place in liquid ,like i collected nickel nanoparticles,,,keep a container on magnet for few hours and then pour upper layers of water.then by using centrifuge u can collect it.

Marius Murariu

Dear Antonio,

I have used SPIONs (super paramagnetic iron oxide nanoparticles), thus I have of interest your question regarding zvi nanoparticles!

Indeed, these NPs are of interest for many applications as it comes from the State of the Art, including the magnetic separation. Please consider bellow some selected information.

Good luck in finding the best info and best regards,

Marius
