Achieving rotary motion at the nanoscale often involves intricate designs and precise control. Some common methods include:
Molecular Motors: These are biological or synthetic molecules that convert chemical energy into mechanical work, enabling rotary motion. Nanoscale Gears: These are tiny gears that interlock to produce rotational movement, similar to macroscopic gears but on a much smaller scale. Optical Tweezers: These use laser beams to trap and manipulate nanoparticles, causing them to rotate. Magnetic Fields: Applying magnetic fields can induce rotational motion in magnetic nanoparticles.
