Stages
- 1.Prevention applications(decision_gate)
The review places prevention first in line with WHO outbreak-control priorities.
Selection: Use nanotechnology to reduce exposure risk through enhanced PPE, antiviral surfaces, and disinfectants.
- 2.Early detection and diagnosis applications(functional_characterization)
The review identifies early detection as a core outbreak-control strategy and maps diagnostic nanotechnologies to that need.
Selection: Use nanoparticle and nanosensor systems for rapid point-of-care and sensitive detection.
- 3.Treatment and therapeutic delivery applications(functional_characterization)
The review places treatment after prevention and diagnosis as the third major strategy.
Selection: Use nanoparticle vaccine and delivery platforms to support treatment efforts and controlled therapeutic delivery.
