This research explores how different types of light can be used to fight biological weapons and dangerous pathogens. The study shows that various forms of light treatment – from UV to visible to infrared – can effectively kill harmful bacteria, viruses, and toxins that might be used in bioterrorism. Key impacts on everyday life: • Provides safer alternatives to chemical disinfectants for cleaning surfaces and equipment • Offers new treatment options for antibiotic-resistant infections • Enables rapid decontamination of air and water systems • Creates possibilities for developing new types of vaccines • Improves safety of blood products and medical supplies
