How to extract silver nanoparticle from colloidal solution?

To synthesize the nanoparticles, I have used electrodes, or metal salt precursor, and applied plasma to solution.
My biggest concern is always to extract the nanoparticles from solution.
I tried to use many ways such as centrifugal process, dry process at 80°C in the oven, filtering the sediment in the bottom of the bottle.
But, I couldn't obtain the intact nanoparticles (because of oxidation in the dry oven or agglomeration), the uniform amount of each sample(different amount of slurry by
centrifuge, loss by filtering).
Because of this problem, I can't measure the exact electrocatalytic activity of the nanoparticles (using CV, LSV test).
I think, slurry (or ink) amount on working electrode and particle morphology and dispersion are very important for that.
So, which method is best to extract the nanoparticles from solution?
