By what mechanism does a nanoparticle detect the presence of a virus?
The article mentions the nanoparticle emitting a kind of signal via "nitrogen vacancy" defects in the diamond structure to signal the presence of a target virus, but glosses how the thing is detected. Are these nanoparticles somehow imprinted with a target signature or something?

NDs harbor a nitrogen-vacancy enabling them to emit fluorescence when illuminated [9,45,46] Basically you design your nano diamonds to bind to a virus, antibody or bacteria and then using imaging you can identify the presence of them in your sample. I don't understand how you ensure your sample is "clean" as in doesn't have non-bound NDs I'm not sure but that's the gist of it from what i gather.
