Respiratory viral pathogens like SARS-CoV-2 easy to test on-site with new nanofilm

Researchers in South Korea have developed a plasmonic isothermal recombinase polymerase amplification (RPA) array chip. This first plasmoinc isothermal PCR technology can detect eight types of pathogens (four bacteria and four viruses) that cause acute respiratory infectious diseases; the analysis takes only 30 minutes.
