“…Here, it is important to discuss about the thermal stability of the diamond nanoparticles. Particlesize measurements performed by dynamic light scattering method have shown 94% of the colloidal particles had an average particle size of 6.6 nm [3]. Moreover, TEM studies have underlined the size of the sp 3 core close to 4 nm surrounded by a sp 2 shell.…”

“…Via this procedure, a high density of diamond seeds (10 10 -10 11 / cm 2 ) can be provided on the substrate prior to CVD growth. Important efforts are at the present time concentrated on the UDD dispersion in liquid suspension [3,4]. The main objective is to prevent the aggregation occurring in the liquid media.…”

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.

“…To initiate the diamond growth, a diamond nano-particle seed layer is deposited onto the substrate by ultrasonification for 30 minutes in a water based suspension of ultra-dispersed (0.1 wt %) nano-diamond particles of typically 5-10 nm size [43]. The samples are then rinsed with deionized water and methanol.…”

Integrated nanophotonic circuits made from wide-bandgap semiconductors offer exciting prospects for advanced sensing applications and broadband optical data processing. Among the available substrates, diamond is particularly appealing due to its long-term stability, biocompatibility and chemical inertness. Because of strong field confinement in diamond waveguides, near-field effects can be efficiently harnessed to realize building blocks for biofunctional circuits in a scalable fashion. Here, we report on the parallel and site-specific functionalization of diamond nanophotonic devices as a promising route towards waferscale bio-photonic systems. We show that arbitrary geometric features can be surface modified using dip-pen nanolithography with a minimum linewidth of 100 nm. We simultaneously functionalize several microring and microdisc resonators with different dies and high precision, allowing us to route fluorescent emission with photonic waveguides to arbitrary locations on chip. Our approach holds promise for hybrid optical systems and nanoscale bioactive devices for robust biomedical and environmental high-throughput sensing applications.2 Photonic components made from diamond have emerged as a promising platform for applications in quantum optics [1][2][3][4], non-linear optics [5,6] and optomechanics [7,8].Because of its remarkable material properties such as broadband optical transparency, high mechanical stability and hardness, high thermal conductivity, and good chemical stability, diamond is used for a wealth of applications in research and industrial environments. In particular the combination of appealing optical properties and biocompatibility make diamond an attractive platform for biophotonic applications [9][10][11]. Nowadays high quality diamond thin films are available on large-scale substrates by relying chemical vapor deposition (CVD) which allows for using waferscale processing techniques to realize functional devices. In this way homogeneous large scale diamond thin films can be achieved (see Supplementary Fig. S2). Using nanofabrication routines developed originally for the electronics industry CVD diamond thin films can be structured into subwavelength photonic devices, which allow for propagating light over centimeter distances, the realization of high quality optical resonators and on-chip interferometers [8,12]. This way the powerful toolbox available to integrated optics can be efficiently utilized to realize a sensitive readout platform for biological signals.In order to employ integrated photonic devices for biosensing suitable links to desired analytes have to be established. Several techniques are commonly employed to functionalize pre-structured photonic substrates, including spincoating with suitable coatings introduced in the liquid phase [13,14] and exposure to reactive agents in the gas phase [15]. While such techniques are suitable to functionalize many photonic components uniformly, it is ultimately necessary to only target specific locations on chip. Deposition of ...

Next, lightly p-doped NCD films with a thickness of ~ 200 nm and a grain size of 50-200 nm were grown on this pre-treated substrate using microwave plasma enhanced chemical vapour deposition (MPECVD) in an ASTeX ® (Applied Science and Technology, Inc., Michigan, USA) reactor equipped with a 2.45 GHz microwave generator.…”

In the framework of developing a fast and label‐free immunosensor for C‐reactive protein (CRP) detection, H‐terminated nanocrystalline diamond (NCD) was functionalised with anti‐CRP antibodies that were physically adsorbed to the surface. Impedance spectroscopy was used to electronically detect real‐time CRP recognition. Different impedance behaviours were observed after CRP addition as compared to after FITC‐labelled ssDNA addition at low (100 Hz) as well as at high frequencies (1 MHz). Physical interpretations of the observed impedance changes were obtained by fitting the data to an equivalent electrical circuit. Concentrations of 1 μM CRP were recognised with a reaction time of 30 minutes. (© 2009 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
