Luminescence characterisation of fluorescent Nanodiamond — •Frederike Erb¹, Boris Naydenov², Ulla Nolte¹, Fedor Jelezko², and Kay-E. Gottschalk¹ — ¹Institute of Experimental Physics, Ulm University, Germany — ²Intstiute of Quantum Optics, Ulm University, Germany

Fluorescent nanodiamonds (FNDs) offer various new imaging and metrology approaches, especially in the life sciences. Nanodiamonds containing nitrogen-vacancy centers as fluorophores emit light in the near-infrared window of bioimaging [1]. Their luminescence properties depend on the environment and thus FNDs can not only be used for bioimaging but also find an application as part of various biosensors. In contrast to dye molecules, FNDs neither blink nor bleach. Moreover, as they are biocompatible, non cytotoxic and do not affect proliferation, they can be used for longtime experiments in live cells [1].

We present luminescence properties of FND and their performance as markers in cells.
