What Are the Methods to Prevent Nanoparticle Aggregation?
Several strategies can be employed to prevent or minimize nanoparticle aggregation:
Surface modification: Coating nanoparticles with polymers or surfactants can provide steric or electrostatic stabilization. pH control: Adjusting the pH of the solution can help in maintaining the charge on the nanoparticles, preventing aggregation. Electrostatic stabilization: Adding charged molecules to the solution can create repulsive forces between nanoparticles, reducing aggregation. Use of dispersants: Adding dispersants can help in maintaining the dispersion of nanoparticles in a medium.
