Our DNA-barcoded aerosols use synthetic DNA, with a unique sequence, to identify each aerosol release point. Our aerosols are water-based, non-toxic, model airborne pathogens, and can be used in occupied spaces safely.

Using a controlled release process for our aerosols, we are able to generate a particle size distribution of our aerosol simulants, correlating well with natural respiratory aerosol size range.

Using multiple DNA tags in our aerosol tracers enables tracking and quantification of different release locations and iterative scenario testing under different building conditions for maximum data accuracy and granularity.

Using Quantitative Polymerase Chain Reaction, or qPCR, we are able to extract data from the collected air samples and quantify DNA concentration levels. We also use surface swabs as a secondary sampling method to complement air sampling.

We provide heatmaps and visualized analytics for equivalent air change rates, airflow, air distribution, particle leakage and migration, and surface deposition levels, along with cost and energy modeling.
