Building's 'Immune System': New Tech Fights Hidden Germs

The Advanced Research Projects Agency for Health is investing $150 million to develop advanced air systems aimed at reducing the spread of illness within indoor spaces. Five research teams are dedicated to creating what they term 'an immune system for every building' as part of the BREATHE program. This initiative focuses on enhancing indoor air quality across various locations, including schools, hospitals, and workplaces.

Virginia Tech is leading a project that uses a biosensor for real-time detection of airborne pathogens and allergens. This technology, which can identify up to 25 different threats, allows for immediate respiratory risk assessments. Software analyzes data from the biosensor, triggering automatic responses like adjusting ventilation or filtration systems to mitigate risks. This advancement significantly speeds up detection from days to near real-time.
