How are experiments with virus with aerosol performed?
Experiments with aerosolized viruses are performed using various methods. One approach involves using simulation models to mimic virus infection and measure the concentration of virus droplet aerosols inside and outside masks in real time, providing information on mask protection rates and respiratory protection . Another method involves developing aerosol filter media made of granular material, such as whey protein nanofibrils and iron oxyhydroxides nanoparticles, which have high filtration efficiencies for both enveloped and non-enveloped viruses . In animal models, aerosol inhalation methods have been established for infecting animals with influenza viruses, including nonhuman primates, allowing for broader infection throughout the lungs . Additionally, a bioaerosol experiment system has been developed to measure virus stability, where virus-laden droplets are generated, evaporated, and suspended for a designed period to evaluate virus exposure risks in indoor environments . Another technique involves the detection of aerosolized viruses using field-effect-transistor-based methods, where virus-antibody-bound particles are delivered to the transistor during detection, indicating the presence of a virus .
