“…As it is well known, ''as-grown'' CVD diamond films are always hydrogen terminated, which generates, in both undoped and B-doped, diamond layers p-type surface conductivity [4][5][6]. Due this effect, even undoped diamond layers can be used as electrode material in electrochemistry [7][8][9]. The role of hydrogen atoms in the diamond layers is investigated for many years and still remains far from full understanding [10,11].…”

The undoped and B-doped polycrystalline diamond thin film was synthesized by hot filament chemical vapor deposition and microwave plasma, respectively. The structural characterization was performed by scanning electron microscopy, X-ray diffraction and Raman spectroscopy. The electrical properties of synthesized diamond layer were characterized by dc-conductivity method and charge deep level transient spectroscopy.

A new fabrication strategy using thermal source of DC arc-discharge plasma is developed in the synthesis of nanodiamond particles. In the fabrication process, a solid mixture of Ni/Si/graphite coarse powders is used as the raw materials, meanwhile the gaseous mixture of H 2 /Ar served as the preparation atmosphere. The well-established arc-discharge plasma is significant in operation under a low gaseous pressure and an acceptable energy condition, and would be potential to become a novel process for synthesis of nanodiamond particles in large scale. The initially formed SiC clusters and the solid solution of Ni(C) particles are crucial in serving as crystal nuclei of diamond and an in situ carbon source which can gradually be released with cooling, respectively. Structural characterizations by high resolution transmission electron microscopy (HRTEM), selected area electron diffraction (SAED), Raman spectra, and X-ray diffraction (XRD) confirm the existence nanodiamond particles, they are typically spherical with 5-20 nm in size. The formation of such nanodiamond particles by the arc-discharge thermal source is discussed in detail on the knowledge of binary phase diagram, constitution of raw materials, and nucleation/growth processes under the experimental conditions.

“…The excessive use of artificial diamonds, especially chemical vapor deposition (CVD) diamonds, has permeated almost every genre of industry, due to their mechanical, conductive, optical, electrochemical and biomedical applications [1][2][3][4][5]. Commencing with harnessing mechanical properties due to the reputation of artificial diamond as the hardest material known, with its superb wear resistance [6,7], the scope of CVD diamond in industrial applications has spread far and wide.…”

“…For instance, apropos biomedical applications, which are at the heart of this study, CVD diamond is appreciated for its features, such as high corrosion resistance, chemical inertness, non-toxicity, immense biocompatibility, low friction coefficient and adjustable electrical conductivity, thereby rendering it a desirable biomaterial [8,9]. In addition to the aforementioned characteristics, its low adsorption and impressively wide potential in non-aqueous and aqueous electrolytes are the properties that make CVD diamond an apt choice of surface coating on the electrodes of electrochemical implantable devices [4,10]. Some of the properties of CVD diamond thin films are given in table 1.…”

The last two decades have witnessed a massive increase in research pertaining to the wide range of use of artificial diamond films, in particular, chemical vapor deposition (CVD) diamond coatings. Exclusive attention has been given to these coatings as a result of their immense biocompatibility, biofunctionality and non-toxic properties, thereby justifying their preference over other conventional long-used biomedical materials. This review study details the deposition chemistry, growth mechanism, forms and determinants of CVD diamond coatings. The sole purpose of this review revolves around the account of potential biomedical applications of CVD diamond coatings to date. Earlier reports along with the most recent trends of employing CVD diamond films in orthopedic, ophthalmological, dental, biosensing, neuronal implant and antibacterial applications, are recapped. The consequential effects of CVD diamondsurface termination, functionalization and doping have also been explained. It is clear that although ample advancement has been made with regard to CVD coatings in the fields of tissue engineering, implantable devices, implant-body electrochemical interactions and fluidic activation, differentiation or immobilization, there is still plenty of room to exploit the full potential of this CVD diamond technology.
