Multiplexed Nanomaterial-Based Sensor Array for Detection of COVID-19 in Exhaled Breath

ACS Nano, Journal Year: 2020, Volume and Issue: 14(9), P. 12125 - 12132

Published: Aug. 18, 2020

This article reports on a noninvasive approach in detecting and following-up individuals who are at-risk or have an existing COVID-19 infection, with potential ability to serve as epidemic control tool. The proposed method uses developed breath device composed of nanomaterial-based hybrid sensor array multiplexed detection capabilities that can detect disease-specific biomarkers from exhaled breath, thus enabling rapid accurate diagnosis. An exploratory clinical study this was examined Wuhan, China, during March 2020. cohort included 49 confirmed patients, 58 healthy controls, 33 non-COVID lung infection controls. When applicable, positive patients were sampled twice: the active disease after recovery. Discriminant analysis obtained signals sensors achieved very good test discriminations between different groups. training set data exhibited respectively 94% 76% accuracy differentiating controls well 90% 95% other infections. While further validation studies needed, results may base for technology would lead reduction number unneeded confirmatory tests lower burden hospitals, while allowing screening solution be performed PoC facilities. considered platform could applied any proper modifications artificial intelligence therefore available diagnostic tool case new outbreak.
