Despite the advances, there are several challenges in achieving precise physical control at the nanoscale:
Scalability: Techniques that work on a small scale often need to be scaled up for practical applications, which can be challenging. Precision: Achieving atomic-level precision consistently is difficult and requires sophisticated equipment. Cost: The tools and materials required for nanoscale manipulation can be expensive. Reproducibility: Ensuring that the same results can be consistently reproduced is crucial but challenging.
