Fabric treated with Duritex™ is self-decontaminating against severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). (A) SARS-CoV-2 titres are decreased when in contact with treated fabric. SARS-CoV-2 [100 μL containing 5 x 105 plaque-forming units (PFU)] was added to the treated or untreated fabric and timepoints of contact were tested. (B) Treated fabric can reduce viral titres over multiple exposures to the virus. SARS-CoV-2 (20 μL containing 1 x 105 PFU) was added to the fabric and allowed to incubate at room temperature for 2 h before the plaque assay. The fabric was exposed every 2 days. For both panels, error bars represent the standard deviation of triplicate samples. The limit of detection (LOD) of the assays was 30 PFU/sample. One-way analysis of variance with Sidak's multiple comparison test was used to determine significance for these assays; ∗∗∗∗P≤0.0001.
