Several factors can influence the physical stability of nanomaterials:
1. Size and Shape: Smaller particles with higher surface area to volume ratios are more prone to aggregation and Ostwald ripening. 2. Surface Chemistry: Surface functionalization can enhance stability by preventing aggregation. 3. Environmental Conditions: Factors such as temperature, pH, and ionic strength can impact stability. 4. Dispersion Medium: The medium in which nanoparticles are dispersed (e.g., water, organic solvents) affects their stability.
