What are the Key Challenges in Developing Passive Nanotechnology Systems?
Despite their potential, passive nanotechnology systems face several challenges:
1. Stability: Ensuring the stability of nanomaterials over time is a significant concern. Nanoparticles can agglomerate or degrade, losing their unique properties.
2. Scalability: Producing nanomaterials at an industrial scale while maintaining their nanoscale properties is challenging. Techniques that work in the laboratory may not always be feasible for large-scale production.
3. Safety and Environmental Impact: The long-term safety and environmental impact of passive nanomaterials are not fully understood. There are concerns about the toxicity and ecological effects of nanomaterials that may enter the environment.
