Searching for M13 bacteriophage with high affinity for nanodiamond particles
Nanodiamonds have potential in biomedical uses, as they are non-toxic and exhibit non-blinking fluorescence behavior when they are enriched with nitrogen vacancy centers. In order for them to be useful in biomedical applications, they need to be functionalized. In this experiment, a pIII library of …
