TLDR
ND particles structure, strategies for surface modification, electrokinetic properties of NDs in suspensions, and a brief overview of the relevant bioapplications are discussed.Abstract:
Diamond has outstanding bulk properties such as super hardness, chemical inertness, biocompatibility, luminescence, to name just a few. In the nanoworld, in order to exploit these outstanding bulk properties, the surfaces of nanodiamond (ND) particles must be accordingly engineered for specific applications. Modification of functional groups on the ND's surface and the corresponding electrostatic properties determine their colloidal stability in solvents, formation of photonic crystals, controlled adsorption and release of cargo molecules, conjugation with biomolecules and polymers, and cellular uptake. The optical activity of the luminescent color centers in NDs depends on their proximity to the ND's surface and surface termination. In order to engineer the ND surface, a fundamental understanding of the specific structural features and sp(3)-sp(2) phase transformations on the surface of ND particles is required. In the case of ND particles produced by detonation of carbon containing explosives (detonation ND), it should also be taken into account that its structure depends on the synthesis parameters and subsequent processing. Thus, for development of a strategy of surface modification of detonation ND, it is imperative to know details of its production. In this review, the authors discuss ND particles structure, strategies for surface modification, electrokinetic properties of NDs in suspensions, and conclude with a brief overview of the relevant bioapplications.read more

TL;DR: It is shown that bright fluorescent nanodiamonds can be produced in large quantities by irradiating synthetic diamond nanocrystallites with helium ions, and the fluorescence is sufficiently bright and stable to allow three-dimensional tracking of a single particle within the cell by means of either one- or two-photon-excited fluorescence microscopy.

Polyurethane sponge functionalized with superhydrophobic nanodiamond particles for efficient oil/water separation
TL;DR: Inspired by the remarkable adhesive ability of dopamine, a feasible approach was developed for the preparation of super-hydrophobic NDs particles as discussed by the authors, which is based on coating hydroxylated NDs with polydopamine (PDA) and subsequent reaction with 1 H,1 H,2 H,2 H -perfluorodecanethiol (PFDT), the resulting f -PDA modified NDs (NDs- f PDA) were firmly anchored onto the skeleton of commercial polyurethane (PU) sponge.
