“…[51] This form of NCD has led to applications in micro-electromechanical systems (MEMS) and nano-electromechanical systems (NEMS), [52][53][54][55][56][57][58] secondary electron emitters, [59][60][61][62] biocompatible coatings, [63][64][65][66][67][68] silicon on diamond substrates, [69][70][71] and sensors. [72,73] As a class, NCD films cover a wide range of materials ranging from films with properties approaching singlecrystal diamond to others which are useful for specialized applications such as field emission, and biomedical implants, even though their specific properties differ from those of single-crystal diamond. Table 1 categorizes the various forms of both NCD and UNCD, and highlights some of their important physical characteristics.…”

The growth and characteristics of nanocrystalline diamond thin films with thicknesses from 20 nm to less than 5 mm are reviewed. These materials contain between 95% and >99.9% diamond crystallites, the balance being made up from other forms of carbon. Within this class of materials there is a continuous range of composition, characteristics, and properties which depend on the nucleation and growth conditions. It is convenient to classify these films as either ultra-nanocrystalline-diamond (UNCD) or nanocrystalline-diamond (NCD) based on their microstructure, properties, and growth environment. In general, UNCD materials are composed of small particles of diamond ca. 2-5 nm in size with sp 2 -carbon bonding between the particles. UNCD is usually grown in argon-rich, hydrogen-poor CVD environments, and may contain up to 95-98% sp 3 -bonded carbon. NCD materials start with high density nucleation, initiating nanometer-sized diamond domains which grow in a columnar manner with the grain size coarsening with thickness. NCD is generally grown in carbon-lean and hydrogen-rich environments. NCD and UNCD exhibit an interesting range of physical properties which find use in X-ray windows and lithography, micro-and nanomechanical and optical resonators, tribological shaft seals and atomic force microscopy (AFM) probes, electron field emitters, platforms for chemical and DNA sensing, and many other applications.

“…[63,65,68,151] Thin film transistors with covalent molecular functionalization have been demonstrated. [72] Most recently, NCD has been used as an optical material to fabricate 'whispering gallery' mode optical resonators, [57] two dimensional photonic crystals, [56,96] and UV transparent electrodes on SiC.…”

“…Also, the carbon terminated surface of diamond offers a wide range of opportunities for covalent grafting of specific bio-receptors onto its surface [19]. Indeed, various routes of proteins immobilisation onto diamond surfaces were reported in the literature [20,21]. Garrido et al [22] showed that it is even possible to pattern the bio-immobilisation using oxidised or hydrogenated diamond surfaces, in this case for bio-FET fabrication.…”

“…1. Briefly, after grafting to the surface the TFAAD molecule is converted to a primary amine by reaction with a reducing agent such as NaBH 4 [25], to produce an amino-terminated surface (i.e., exposing -NH 2 groups at the surface. A bifunctional cross-linked such as sulfosuccinimidyl 4-(N-maleimidomethyl) cyclohexane-1-carboxylate (SSMCC) is then used link thio-modified DNA to the amino-terminated surface.…”

Previous work has shown that organic alkenes will graft to covalent semiconductors such as diamond and silicon. Here, we demonstrate that organic alkenes can be grafted to the surfaces of metal oxide semiconductors, including TiO2 in nanocrystalline thin films and as single‐crystal anatase(001) epitaxial films grown on SrTiO3(001) substrates. The resulting layers can be used as a starting point for linking biomolecules such as DNA to metal oxide surfaces. Initial results are presented showing that this chemistry can also be applied to graft molecular layers to zirconium oxide thin films. (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
