“…Moreover, previous Fourier Transform Infrared (FTIR) spectra underlined that UDD termination involves the presence of hydroxyls (C-OH), ether (C-O-C) and carbonyls (C=O) groups [7][8] resulting from the severe acid treatment applied prior the dispersion of diamond nanoparticles in water. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 The morphology of the nanoseeded surface is depicted on the figure 2.…”

The thermal stability of Ultra Dispersed Diamond on silicon surfaces has been investigated. Samples have been annealed under Ultra-High Vacuum conditions. The evolution of the carbon binding states at the surface has been monitored sequentially by XPS and XEELS. After annealing at 1173 K, sp(3) seeds present initially have been significantly modified. Contrary to lower temperature, no diamond has been detected either by XPS or by FEG-SEM after a short growth step. XPS spectra indicate the formation of silicon carbide.

“…Each scaffold contained 1 µg of BMP-2. Acid purifi ed detonation diamond (Gansu Lingyun Corp., Lanzhou, China) was subjected to attrition milling using a method previously described [ 27 ] achieving a narrow size distribution at ≈5 nm particle diameter (measured by dynamic light scattering in water) and very low agglomeration of the diamond particles. Scaffolds were modifi ed with the nDP solution (2 wt%, i.e., 20 mg mL −1 ) by a vacuum technique: 0.5 mL nDP solution and one scaffold were put in a glass beaker and perfused in vacuum (Oerlikon Leybold, TRIVAC D 65B).…”

The aim is to evaluate the effect of modifying poly[( L -lactide)-co-(ε-caprolactone)] scaffolds (PLCL) with nanodiamonds (nDP) or with nDP+physisorbed BMP-2 (nDP+BMP-2) on in vivo host tissue response and degradation. The scaffolds are implanted subcutaneously in Balb/c mice and retrieved after 1, 8, and 27 weeks. Molecular weight analysis shows that modifi ed scaffolds degrade faster than the unmodifi ed. Gene analysis at week 1 shows highest expression of proinfl ammatory markers around nDP scaffolds; although the presence of infl ammatory cells and foreign body giant cells is more prominent around the PLCL. Tissue regeneration markers are highly expressed in the nDP+BMP-2 scaffolds at week 8. A fi brous capsule is detectable by week 8, thinnest around nDP scaffolds and at week 27 thickest around PLCL scaffolds. mRNA levels of ALP, COL1α2, and ANGPT1 are signifi cantly upregulating in the nDP+BMP-2 scaffolds at week 1 with ectopic bone seen at week 8. Even when almost 90% of the scaffold is degraded at week 27, nDP are observable at implantation areas without adverse effects. In conclusion, modifying PLCL scaffolds with nDP does not aggravate the host response and physisorbed BMP-2 delivery attenuates infl ammation while lowering the dose of BMP-2 to a relatively safe and economical level.

“…2 A nanodiamond with a mixed composition of surface groups can be oxidised and terminated with oxygencontaining functional groups or reduced to produce a homogeneous hydrogen surface termination bead milling and sonication (Krüger et al 2005;Fu et al 2007;Faklaris et al 2008). Through a combination of these techniques we were first able to observe NV centres in isolated 5-nm nanodiamonds (Bradac et al 2010).…”

In recent years, nanodiamonds have emerged from primarily an industrial and mechanical applications base, to potentially underpinning sophisticated new technologies in biomedical and quantum science. Nanodiamonds are relatively inexpensive, biocompatible, easy to surface functionalise and optically stable. This combination of physical properties are ideally suited to biological applications, including intracellular labelling and tracking, extracellular drug delivery and adsorptive detection of bioactive molecules. Here we describe some of the methods and challenges for processing nanodiamond materials, detection schemes and some of the leading applications currently under investigation.
