Photoluminescent diamond nanoparticles for cell labeling: study of the uptake mechanism in mammalian cells.

Orestis Faklaris, +11 more
- 28 Oct 2009 - 
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.
Journal ArticleDOI

Photoluminescent diamond nanoparticles for cell labeling: study of the uptake mechanism in mammalian cells

Orestis Faklaris, +11 more
- 07 Jul 2009 - 
TL;DR: In this article, the authors used photoluminescent nanodiamonds of size <50 nm for intracellular labeling and investigated the mechanism of their uptake by living cells, by blocking selectively different uptake processes and converging data indicate that it is clathrin mediated.
Journal ArticleDOI

Surface properties of hydrogenated nanodiamonds: a chemical investigation.

Hugues A. Girard, +6 more
- 07 Jun 2011 - 
TL;DR: The chemical reactivity of fully hydrogenated High Pressure High Temperature (HPHT) nanodiamonds (H-NDs) towards grafting is reported, suggesting that C-H related surface properties remain dominant even on particles at the nanoscale.
Journal ArticleDOI

Early stages of surface graphitization on nanodiamond probed by x-ray photoelectron spectroscopy

Tristan Petit, +4 more
- 19 Dec 2011 - 
TL;DR: In this paper, the early stages of graphitization on detonation nanodiamond during sequential annealing treatments under vacuum using x-ray photoelectron spectroscopy were investigated.
Journal ArticleDOI

Carboxylated nanodiamonds are neither cytotoxic nor genotoxic on liver, kidney, intestine and lung human cell lines

Vincent Paget, +10 more
- 12 Aug 2014 - 
TL;DR: Overall, it is shown that NDs effectively entered the cells but NDs do not induce any significant cytotoxic or genotoxic effects on the six cell lines up to an exposure dose of 250 µg/mL.
