This is wild! Researchers at Washington University in St. Louis have created a prototype real-time monitor that can detect any of the SARS-CoV-2 virus variants in a room in about 5 minutes. They adapted a micro-immunoelectrode to use llama nanobodies that recognize SARS-CoV-2 spike proteins combined with a wet-cyclone sampler running at 1000 l/m. They oxidize tyrosines on the virus surface and measure with square wave voltammetry. #Covid https://www.nature.com/articles/s41467-023-39419-z
