“…Chemical vapor deposition, CVD, is the most popular technique for depositing BDD films at low pressures. 20 The doping of diamond becomes necessary for analytical applications, since pure diamond does not show relevant electrochemical properties. A BDD electrode has unique characteristics; the main and perhaps the most exploited one is its potential window of approximately 3.0 V, high electroactivity in water, and production of a low background current when compared to a glassy carbon electrode, or any other carbon electrode.…”

The aim of this work was to develop an electrochemical cell and a methodology based on an amperometric determination of hydrogen peroxide in whitening gel samples under a boron-doped diamond electrode using flow injection analysis. Different parameters were evaluated to obtain the best conditions of analysis: among them, the flow of electrolyte at 2.8 mL min, the loop sampling 175 μL (28.5 cm), an analytical length of 159 μL (25 cm) and an applied potential of +0.60 V vs. Ag/AgCl. The proposed method was suitable in terms of precision of results (RSD <10%); the accuracy was confirmed in the analysis of the gels through addition and recovery studies with results between 74 and 107%. The method was then applied to the analysis of tooth-whitening gel samples, acquired in different cities of the region. Regarding the results, a medium concentration value of 2.39% (w/w) was observed.

“…Chemical vapor deposition (CVD), assisted by a variety of excitation energies, has been the major technique for growing diamond thin films. 8,9) However, CVD can provide only a low throughput of film formation while requiring a complicated apparatus. Recently, nanoparticles of diamond have become commercially available, 10,11) which has motivated the development of simple and low-temperature film deposition methods, such as aerosol spraying and layer-by-layer deposition.…”

Thin films of diamond nanoparticles were prepared by electrophoretic deposition (EPD) using 0.5 wt % dispersions in water, ethanol, and 2-propanol. The film growth rate increased with increasing voltage applied to the electrodes. However, an excessive increase in voltage caused the degradation of film morphology. The optimum voltage was 4 V with an electrode separation of 5 mm. The film growth rate was higher in organic solvents than in water. The deposited film had a smooth surface with an average surface roughness comparable to the size of primary particles of the source material. It is notable that the EPD films had a considerably higher physical stability than spin-coated and cast films. The stability was further improved by thermally annealing the films. IR analysis revealed that the diamond nanoparticles have carboxy and amino groups on their surfaces. It is considered that the stability of the EPD films originate from a chemical reaction between these functional groups.

Synthetic diamond and conductive, doped forms of diamond are ideally suited materials for scanning probe microscopy tips due to their inherent physical, chemical, and mechanical properties. In particular for atomic force microscopy (AFM) and related techniques, which require a conductive tip in permanent contact to the sample surface, boron‐doped diamond (BDD) is an excellent material. Only few examples have so far been demonstrated using boron‐doped diamond microelectrodes as probes for scanning electrochemical microscopy (SEM) or AFM‐SECM. This review focuses on the state‐of‐the‐art using diamond‐coated SPM tips and conductive boron‐doped diamond as probe material discussing advantages and disadvantages.
