Several techniques are employed in nanotechnology for the separation of nanomaterials. Some of the most common are:
1. Centrifugation: Utilizes centrifugal force to separate components based on their size, shape, and density. 2. Filtration: Employs a porous medium to separate particles from fluids. Nanofiltration is particularly useful for separating nanoparticles from liquids. 3. Membrane Separation: Involves the use of a selective barrier to separate particles based on size and other properties. It includes techniques like ultrafiltration and reverse osmosis. 4. Magnetic Separation: Uses magnetic fields to separate magnetic nanomaterials from non-magnetic ones. 5. Chromatography: A versatile technique that separates nanoparticles based on their interaction with a stationary phase and a mobile phase.
