What is Non-Mechanical Nanotechnology?
Non-mechanical nanotechnology refers to the manipulation and utilization of materials and devices at the
nanoscale that do not rely on traditional mechanical components. Instead, these technologies leverage chemical, electrical, optical, and magnetic principles to achieve their functionality. This approach contrasts with
mechanical nanotechnology, which often involves moving parts and components.
