Despite its potential, movement control at the nanoscale faces several challenges: 1. Brownian Motion: The random movement of particles in a fluid, known as Brownian motion, can interfere with the precise control of nanoparticles. 2. Energy Efficiency: Powering nanodevices and maintaining their movement control requires highly efficient energy sources. 3. Scalability: Developing methods that are scalable for industrial applications is a significant hurdle. 4. Integration: Integrating nanoscale movement control systems with existing technologies poses technical challenges.
