Various techniques are employed to achieve sorting at the nanoscale:
Centrifugation: Utilizes centrifugal force to separate particles based on density and size. Electrophoresis: Applies an electric field to move particles according to their charge and size. Filtration: Uses membranes with specific pore sizes to separate particles. Magnetic Separation: Employs magnetic fields to sort magnetic nanoparticles from non-magnetic ones. Optical Tweezers: Uses laser beams to manipulate and sort particles based on their refractive index and size.
