The integration of nanotechnology in the realm of CBRN threats brings forth several ethical and regulatory challenges:
1. Dual-Use Dilemma: Technologies designed for beneficial purposes can also be repurposed for malicious use. This dual-use nature of nanotechnology necessitates stringent oversight. 2. Regulation: The rapid advancement of nanotechnology often outpaces existing regulatory frameworks, making it difficult to ensure safe and secure usage. 3. Privacy Concerns: The deployment of nanosensors for detection purposes can raise privacy issues, as these sensors could potentially be used for surveillance.
