Diafiltration of Silica and Au nanoparticlesgpgoodrich2005-05-09Click here to register.
Hello,
I need to wash 100 nm silica particles, and do a buffer exchange from H20 to ethanol. I have tried the microkros 0.05 PS membranes, but the particles always aggregate and plug the membrane.

I also need to wash and concentrate 150 nm bare gold particles. I have tried the above 0.05um PS microkros but the particles stick to the membranes. Any suggestions?

Thanks for visiting.
