Examples of detection systems for SARS-CoV-2: (A) Nucleic Acids Amplification Testing-reverse transcription-polymerase chain reaction (NAAT-RT-PCR, gold standard for diagnostic), colorimetric real-time Loop-Mediated Isothermal Amplification (RT-LAMP) reaction; (B) detection of viral antigens and IgG/IgM antibodies using lateral flow tests/ELISA (enzyme-linked immunoassays); (C) schematic representation of a biosensor for SARS-CoV-2 detection; (D) schematic workflow of CovidNudge Point of Care diagnostic for SARS-CoV-2 (adapted from Gibani et al. [175]).
