Frontiers | Detecting SARS-CoV-2 in the Breath of COVID-19 …

17/03/2021· In the COVID-19 outbreak year 2020, a consensus was reached on the fact that SARS-CoV-2 spreads through aerosols. However, finding an efficient method to detect viruses in aerosols to monitor the risk of similar infections and enact effective control remains a great challenge. Our study aimed to build a swirling aerosol collection (SAC) device to collect viral particles in exhaled breath and …

Frontiers | Detecting SARS-CoV-2 in the Breath of COVID-19 …

17/03/2021· Laboratory tests of the SAC device using aerosolized SARS-CoV-2 pseudovirus indicated that the SAC device can produce a positive result in only 10 s, with a collection distance to the source of 10 cm in a biosafety chamber, when the release rate of the pseudovirus source was 1,000,000 copies/h. Subsequent clinical trials of the device showed three positives and 14 negatives out of 27 patients in …

Proof of concept for real-time detection of SARS CoV-2 infection …

02/06/2021· Introduction. Viruses alone don’t produce volatile organic compounds (VOCs), but virus-infected cells do [], and these can be targeted for VOC-based disease detection [].Such detection can be conducted with trained animals such as dogs [3, 4], but large-scale animal deployment is a turn, electronic noses (eNoses) are machines that mimic the animal olfactory system [5–7], and these …

Optical Biosensors for Virus Detection: Prospects for …

29/10/2020· SARS-CoV-2’s DNA-RNA hybridization is used in RT-PCR amplification and can be induced by thermal exposure at a temperature slightly lower than the nucleic acid strand melting temperature. 105 Qiu et al. used this phenomenon to develop a dual-functional gold nanoisland-based biosensor using both thermoplasmonic heating (to induce signal amplification) and SPR imaging to …
