Probing the Activity of Matrix Metalloproteinase II with a Sequentially Click-Labeled Silica Nanoparticle FRET Probe

Zusammenfassung

Selective double click labeling: The determination of nanomolar concentrations of matrix metalloproteinase II is made possible through the use of a nanoprobe that consists of fluorescently doped silica nanoparticles to which a FRET-based enzyme substrate has been conjugated through sequential click reactions.
