Several techniques are employed to achieve effective solvent dispersion:
Ultrasonication: This technique uses high-frequency sound waves to break apart nanoparticle agglomerates and distribute them uniformly in the solvent. Mechanical stirring: A simple and commonly used method where nanoparticles are dispersed by stirring the solution vigorously. High-shear mixing: This involves using a rotor-stator device that creates intense shear forces to break apart and disperse nanoparticles. Ball milling: A mechanical process where nanoparticles are ground in the presence of a solvent to achieve fine dispersion.
