Velotta explains that a solution of free gold nanoparticles will have a certain colour due to the wavelengths of light that the solution absorbs. But if you add a sample containing SARS-CoV-2 to the solution, the resulting aggregation of the virus and the nanoparticles causes a shift in the absorption peak, and the colour of the solution changes.
