An Exhaled Breath Sampler Based on Condensational Growth and Cyclone Centrifugation (BSCC)

An exhaled breath sampler based on condensational growth and cyclone centrifugation (BSCC) was developed evaluated. The BSCC increases the size of aerosols through then collects them as liquid sample via centrifugation. This enables rapid collection eliminates certain pre-treatment steps for pathogenic microorganism analysis. Laboratory-generated were mixed with saturated water vapor to simulate breath, efficiency virus infectivity conservation approximately 66.7% 100 nm increased nearly 100% 3 µm aerosols. Besides, maintained 93.5% atomized model aerosol (Pseudomonas bacteriophage Phi6). When collecting samples from nine volunteers, average rate 248.7 µL min–1. achieved superior overall performance (i.e., 60% high 40% higher efficiency) compared RTube, a commercial used sampler, indicating its potential diagnosis respiratory infection measurements viral
