Several methods are employed for the removal process in nanotechnology:
1. Centrifugation: Utilizes centrifugal force to separate particles based on their size, shape, and density. 2. Filtration: Employs porous membranes to separate particles from a solution. 3. Dialysis: Uses a semi-permeable membrane to remove small molecules from larger nanoparticles. 4. Chemical Treatment: Involves the use of chemicals to dissolve or react with contaminants, making them easier to remove. 5. Ultrasonic Cleaning: Uses high-frequency sound waves to agitate particles and remove contaminants from surfaces.
