question: Can you summarize and explain for me what you want to tell in the article below? 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 Inactivate SARS-CoV-2 in Different Environments Outside the Patient SARS-CoV is highly stable at room temperature and at 4 °C, but it is inactivated by ultraviolet light at 254 nm, highly alkaline or acidic conditions of pH >12 or pH <3, respectively, or by brief (e.g., 5 min) heat treatment at 65 °C.
