these probes can be visualized by standard fluorescence imaing instruments including fluorescence microscopes, TIRF, gel scanners, flow cytometry, optical animal scanners, clinical cameras etc. They also have long fluorescence lifetimes and so can be imaged by fluorescence lifetime instruments. What the article didn't delve into is that because of an additional magnetic sensitivity that the nanodiamonds have, we can improve image quality and imaging deeper into tissue with an additional hardware piece that we can add on to existing systems or in a stand-alone system that is cheaper to be tailored to n=only nanodiamonds. if you want more info on this, I can elaborate or have a chat with you
