Hello Manila,

Can I ask why dialysis should be avoided in your case ? Dialysis are very effective, even more with saline solution (See paper of Thomas Heinze Group on Cellulose and ionic liquids).

Otherwise, extraction with organic solvant is another techniques sometines reported. But, in my opinion, the most powerfull technique is the extraction with supercritical CO2, which is unfortunately not easily accessible due to the price of the device. If you can have access to such device, you should definitely take a look at this possibility!

Best regards,

I think you can think about an optical tweezer or some other optical trapping techniques...

But I am not very much sure about it.....!
