Spot Sampler for Biological Collection
What it does:
The VIVAS is designed for efficient, viable capture of virus, bacteria and other bio-aerosols into a water solution.
How it works:
VIVAS uses the water-condensation growth tube to gently enlarge submicrometer airborne particles to form micrometer-sized droplets that are gently deposited into liquid.
Due to the condensational enlargement, collection efficiencies are above 90% for particles as small as 8 nm, and as large as 10µm.
In collaboration with colleagues at the University of Florida, a forerunner of the “VIVAS”, was tested with influenza virus, and found to be more than an order of magnitude more efficient than the BioSampler.
