Functionalized Green Fluorescent Nanodiamonds
Fluorescent nanodiamonds are a chemically robust, infinitely photostable, and biocompatible fluorophore with a range of functional surface chemistries. Relevant applications include fiducial marking, super-resolution microscopy, multiphoton microscopy, time-gated microscopy, and correlative microscopy.
Our selection of nanodiamonds containing NVN centers with green fluorescence include particles produced from natural diamond and from diamond of synthetic origin of type Ib using a patented process of rapid thermal annealing for the later. Fluorescent nanodiamonds of synthetic origin have higher brightness than particles produced from natural diamond.
