As the world continues to grapple with the COVID-19 pandemic, an international team of researchers have published a review of the best techniques to collect airborne aerosols containing viruses.
In the review, which was published by the
Science of the Total Environment journal, a team led by the University of Surrey concluded that the most effective way to collect and detect airborne pathogens, particularly viruses, was to use cyclone sampling techniques.
For example, the sampler draws the air through the cyclone separator. It then uses centrifugal forces to collect the particles on a sterile cone containing the liquid collection vessel, such as DMEM (Dulbecco s minimal essential medium). The collected sample can then be readily used for any analysis for virus detection.
