Try to add some surfactants to avoid aggregating nanopartcles.

Shuvendu Tripathy

Check the zeta potential and use ammonium salt of polyacrylic acid

It is a very good dispersing agnet

Dimitar P. Mitev

Sonication using the help of micronsized zirconia beads and subsequent fractionation could be of significant benefit for deaggregation, in some cases.

Titus Sobisch

You should synthesize or buy stabilized nanoparticles in fluid dispersion. Otherwise particles get strongly aggregated due to interparticle bonds.
