Several techniques are employed for scooping at the nanoscale. These include:
1. Atomic Force Microscopy (AFM): AFM uses a sharp tip to interact with the surface of a sample, allowing for the isolation and manipulation of nanoscale particles. 2. Optical Tweezers: This method uses highly focused laser beams to trap and move small particles, enabling precise manipulation at the nanoscale. 3. Magnetic Tweezers: These use magnetic fields to control the movement of magnetic nanoparticles, which can be used to isolate specific particles from a mixture. 4. Microfluidics: This technique involves the use of tiny channels to manipulate fluids containing nanoparticles, enabling their isolation and study.
