Colloidal stability can be achieved through various mechanisms:
- Electrostatic Stabilization: By imparting a surface charge to the particles, electrostatic repulsion can prevent aggregation. - Steric Stabilization: The use of polymers or surfactants adsorbed on the surface of nanoparticles can provide a steric barrier to aggregation. - Electrosteric Stabilization: A combination of electrostatic and steric stabilization, where both charges and steric hindrance work together to maintain stability.
