Porous boron doped diamond for dopamine sensing: Effect of boron doping level on morphology and electrochemical performance

Next-Generation Diamond Electrodes for Neurochemical Sensing: Challenges and Opportunities

“…In some cases, the increased background currents can be large enough to saturate the input amplifier, in which case analog background subtraction can be applied using a UEI instrument with HDCV software and subtracting headstage [ 181 ]. Besides electrochemically treated BDD, porous BDD offers unique advantages including the large active area, strong surface adsorption, and high electron transfer properties [ 182 ], making it a good electrode material for highly sensitive and selective NT detection. Porous BDD can be created using plasma consisting of equal portions of H 2 and Ar [ 183 ], or nanodiamond seeded SiO 2 nanofiber templates [ 182 ], or vertically aligned carbon nanotubes scaffold [ 184 , 185 ].…”

Similarly, May et al fabricated high-surface-area BDD electrodes using “black silicon”, a synthetic nanostructured material that contains high-aspect-ratio nano-spikes or needles, as a template during BDD synthesis [ 186 ].…”

Voltammetric study of triazole antifungal agent terconazole on sp3 and sp2 carbon-based electrode materials

“…It follows from Table 1, which summarizes the characteristics and limits of detection of the voltammetric methods that their oxidation occurs at potentials ranging from ca +0.5 V to +0.75 V on carbon-based electrodes, including boron doped diamond (BDD). This material offers advantageous properties for electroanalysis of organic compounds, including mechanical stability, low background current, wide potential window especially in the region of positive potentials and usually low adsorbability of reaction by-products and products resulting in fouling resistivity [23][24][25]. Its electrochemical properties are influenced by the surface pretreatment.…”

“…byproducts with the mentioned surfaces and similar kinetics of electron transfer. It is important in the view of other studies, where substantial differences in positioning of anodic/cathodic signals were reported when comparing BDD with other carbon-based electrodes[23,35,36] or when comparing O-, H-and polished BDD surfaces, with the Oterminated one, observed to inhibit electron transfer and thus shifting anodic/cathodic signals to more positive/negative potentials[37].The second peak appearing at more positive potentials at ca +1.0 V -+ 1.25 V is well observable on O-BDD and p-BDD in all media and on H-BDD in acidic media. On the other hand, it is absent on CVs recorded on the sp 2 carbon electrode materials due to its low intensity or narrower potential windows of the latter electrodes.…”

A cost-efficient approach for simultaneous scanning electrochemical microscopy and scanning ion conductance microscopy

“…Boron-doped diamond (BDD) is a material exhibiting high chemical stability, inertness, and a wide potential window; therefore, being considered a potent electrode material [18,19]. Porous BDD provides higher surface area, which results in, e.g., higher sensitivity and selectivity [20,21]. Non-porous, planar, BDD samples have been investigated via SECM and a non-uniform distribution of electrochemical activity was found [22,23].…”
