A nanodiamond is forever: Fluorescent nanodiamonds for in vitro and in vivo biological imaging

Friday December 1, 2017
3:30 pm

 Presenter:  Keir Neuman, NIH
 Series:  Physics and Astronomy Colloquium
 Abstract:  Fluorescent nanodiamonds (FNDs) are biocompatible particles with indefinite photo-stability that makes them superior imaging probes that could replace commonly used fluorescent probes for a wide range of applications. The negatively charged nitrogen-vacancy (NV−) center is a defect in the diamond lattice consisting of a substitutional nitrogen and a lattice vacancy that form a nearest-neighbor pair. NV− centers are fluorescent sources with remarkable optical properties including quantum efficiency near unity, indefinite photo-stability, i.e., no photo-bleaching or blinking, broad excitation spectra, and exquisitely sensitive magnetic field-dependent fluorescence emission. I will describe the production and unique features of FNDs and illustrate their unique capabilities with several examples ranging from high-resolution three-dimensional single-molecule tracking to background-free in vivo imaging.
