Summary
Man-made micro/nanomotors offer advanced security solutions for detecting and neutralizing chemical and biological warfare agents (CBWA). These tiny machines enable efficient threat elimination in challenging environments, enhancing defense capabilities.
Area of Science:
- Nanotechnology
- Chemical Engineering
- Defense Science
Background:
- Man-made micro/nanomotors possess novel capabilities applicable to security and defense.
