Abstract

This communication describes a novel water-soluble membrane prepared from chitosan intended for SARS-CoV-2 viral nucleic acid collection and detection. The CSH membrane formed from nanofibers shows promising potential in the quantitative determination of the SARS-CoV-2 viral nucleic acids at a concentration of 10² copies per L in air. The sponge-like structure which allows gas to pass through for collection of viral nucleic acids potentially provides simple, fast, and reliable sampling as well as detection of various types of airborne viruses.
