What Role Do pH Levels Play in Nanoparticle Stability?
Nanoparticles can be highly sensitive to changes in pH, which can affect their stability. In aqueous solutions, variations in pH can lead to aggregation or precipitation of nanoparticles. For instance, gold nanoparticles are known to aggregate under acidic conditions. Therefore, maintaining an optimal pH is crucial for preserving the dispersion and effectiveness of nanoparticles in various applications.
