Controlling the aggregation state is essential for the consistent performance of nanomaterials. Several strategies can be employed:
Surface Functionalization: Modifying the surface of nanoparticles with specific molecules to control their interactions. Stabilizing Agents: Adding chemicals that prevent aggregation by creating a repulsive barrier. pH and Ionic Strength Control: Adjusting the pH and ionic strength of the medium can influence the electrostatic interactions between nanoparticles.
