Every step in the procedure is highly significant: Thermal drying prevents oxidation by moisture, coating the nanoparticles with oleic acids facilitates their wetting and dispersal in nonpolar media, probe sonication provides the nanoparticles with the appropriate degree of shear needed to deagglomerate, and gentle bath sonication ensures that the nanoparticles are not broken.
