Photoluminescent diamond nanoparticles for cell labeling: study of the uptake mechanism in mammalian cells.
Orestis Faklaris,Vandana Joshi,Theano Irinopoulou,Patrick Tauc,Mohamed Sennour,Hugues A. Girard,Céline Gesset,Jean-Charles Arnault,Alain Thorel,Jean-Paul Boudou,Patrick A. Curmi,François Treussart +11 more
TL;DR: It is shown that nanodiamonds enter cells mainly by endocytosis, and converging data indicate that it is clathrin-mediated, and the results pave the way for the use of photoluminescent nanod diamonds in targeted intracellular labeling or biomolecule delivery.

Electrostatic Grafting of Diamond Nanoparticles: A Versatile Route to Nanocrystalline Diamond Thin Films
Hugues A. Girard,Sandrine Perruchas,Céline Gesset,Marc Chaigneau,Laetitia Vieille,Jean-Charles Arnault,Philippe Bergonzo,Jean-Pierre Boilot,Thierry Gacoin +8 more
TL;DR: A straightforward method to disperse diamond nanoparticles on a substrate by taking advantage of the electrostatic interactions between the nanodiamonds and the substrate surface coated with a cationic polymer, which leads to reproducible and homogeneous large-scale nanoparticle deposits independent of the substrate's nature and shape is reported.

Large-area high-quality single crystal diamond
TL;DR: In this paper, the two major current approaches of synthesizing single crystal diamond by chemical vapor deposition are described, and the state of the art for both concepts is summarized, and current as well as potential future applications are discussed.
