“…High Resolution Transmission Electron Microscopy (HRTEM) revealed faceted shapes with sharp edges corresponding to fractured crystallographic planes. In few cases, quasi spherical nanodiamonds smaller than 10 nm were obtained by HPHT milling [41,42]. More recently, 70-80 nm nanodiamonds were also produced from polycrystalline CVD diamond by bead assisted sonic disintegration (BASD) [43].…”

“…These particles showed good photostability and spin properties. 35,36 A similar ball milling method to produce sub-20-nm FNDs has also been developed recently by Su et al 37 starting with 100-nm particles instead. The NV centers in FNDs can be present in either the negatively charged state or the neutral state, or both.…”

The first demonstration of nanodiamonds (NDs) for cellular fluorescence imaging was reported in 2005. It has since then aroused considerable interest among scientists working in the field of diamond and related materials. A large number of researches have been conducted, aimed to develop this novel nanomaterial as diagnostic, imaging, and therapeutic agents in biomedicine. There have been more than 20 review articles and book chapters published on this topic in the past 8 years. With the recent development of nanotechnologies and photonics, the ND-based bioimaging has been taken to a new level. In this topic review, we will focus our attention on the recent advances in the development of NDs as versatile bioimaging agents for both in vitro and in vivo applications. Emerging new technologies including multiphoton excitation imaging, superresolution imaging, optically detected magnetic resonance imaging, cathodoluminescence imaging, and photoacoustic imaging are discussed.

“…The diameter of the isolated nano-diamond was also set to 30 nm in all calculations. This is a typical size for a nano-diamond with luminescence properties [36][37][38]. The factor of 0.5 in the denominator is due to P 0 being calculated along the arc length of a full circle, whereas P air was calculated over a semicircle in the air half-space.…”

Dipole Emission to Surface Plasmon-Coupled Enhanced Transmission in Diamond Substrates with Nitrogen Vacancy Center- Near the Surface

For distances less 10 nm, a total energy transfer occurs from a quantum emitter to a nearby metallic surface, producing evanescent surface waves that are plasmonic in nature. When investigating a metallic nanohole supported on an optically dense substrate (such as diamond with nitrogen vacancy center), the scattering occurred preferentially from the diamond substrate towards the air for dipole distances less 10 nm from the aperture. In addition, an enhancement to the dipole's radiative decay rate was observed when resonance of the aperture matched the emitters wavelength. The relationship between an emitter and a nearby resonant aperture is shown to be that of the resonance energy transfer where the emitter acts as a donor and the hole as an acceptor. In conjunction with the preferential scattering behavior, this has led to the proposed device that operates in transmission mode, eliminating the need for epi-illumination techniques and optically denser than air superstrates in the collection cycle, hence making the design simpler and more suitable for miniaturization. A design criterion for the surface grating is also proposed to improve the performance, where the period of the grating differs significantly from the wavelength of the surface plasmon polaritons. Response of the proposed device is further studied with respect to changes in nitrogen vacancy's position and its dipolar orientation to identify the crystallographic planes of diamond over which the performance of the device is maximized.
