Can you explain the figure? When I read it myself, I do not understand exactly what is meant by the article. It would be nice if you could highlight the important points. You can use them in a figure or diagram to explain. thank you and hava a nice day :) Article: Nanotechnology Tools to Detect SARS-CoV-2 Standard procedures for detecting the virus from nasopharyngeal and/or oropharyngeal swabs have been reviewed recently and are primarily based on reverse transcription polymerase chain reaction (RT-PCR). Here, we would like to mention some preliminary ideas on nanotechnology-based assays to monitor the presence of SARS-CoV-2. A simplified test and variants thereof to detect viral proteins (e.g., HIV or influenza virus) without the need for expensive equipment is based on the color change of Au NPs bound to antibodies. Similar to the enzyme-linked immunosorbent assay (ELISA) antibodies coupled…
