Several strategies can be employed to improve the stability of nanoparticle dispersions:
1. Surface Functionalization: Coating nanoparticles with polymers or surfactants can provide steric stabilization. 2. pH Adjustment: Adjusting the pH to levels where the nanoparticles have a high zeta potential can enhance stability. 3. Use of Dispersing Agents: Adding chemicals that promote dispersion, such as surfactants or coupling agents, can improve stability. 4. Ultrasonication: Applying ultrasonic energy can break up agglomerates and enhance dispersion.
