“…Surprisingly, the synthesized diamond films remained stable (with little transformation) for storage time >1.5 years at room temperature (about 25 8C) in a dark cupboard. The observed stability of the diamond films for >1.5 years in the absence of direct light rays is in agreement with the previous observations reported in the literature [28][29][30][31]. Going by Eq.…”

Vertical distribution of nitrogen-vacancy centers in diamond formed by ion implantation and annealing

Etching experiments were performed that reveal the vertical distribution of optically active nitrogen-vacancy (NV) centers in diamond created in close proximity to a surface through ion implantation and annealing. The NV distribution depends strongly on the native nitrogen concentration, and spectral measurements of the neutral and negatively-charged NV peaks give evidence for electron depletion effects in lower-nitrogen material. The results are important for potential quantum information and magnetometer devices where NV centers must be created in close proximity to a surface for coupling to optical structures.

“…Focusing on multiple detection of vesicular release, arrays with up to 64 or even 10×10 electrodes with subcellular dimensions have been produced 12,13 , thus allowing a multi-site detection from chromaffin, PC-12 cells, striatal slices [17][18][19][20] and the coupling of amperometry with fluorescence microscopy 21,22 . An appealing substrate material for these applications is diamond, which offers a wide spectrum of physical-chemical properties which are crucial for the realization of integrated planar sensors, namely: wide optical transparency from infrared (IR) to near ultraviolet (NUV), high chemical inertness 23 , good biocompatibility 24 and the possibility of directly writing sub-superficial graphitic microelectrodes by means of MeV ion beam lithography [25][26][27][28][29][30][31] .…”

Microelectrode Arrays of Diamond-Insulated Graphitic Channels for Real-Time Detection of Exocytotic Events from Cultured Chromaffin Cells and Slices of Adrenal Glands

A microstructured graphitic 4 × 4 multielectrode array was embedded in a single-crystal diamond substrate (4 × 4 μG-SCD MEA) for real-time monitoring of exocytotic events from cultured chromaffin cells and adrenal slices. The current approach relies on the development of a parallel ion beam lithographic technique, which assures the time-effective fabrication of extended arrays with reproducible electrode dimensions. The reported device is suitable for performing amperometric and voltammetric recordings with high sensitivity and temporal resolution, by simultaneously acquiring data from 16 rectangularly shaped microelectrodes (20 × 3.5 μm(2)) separated by 200 μm gaps. Taking advantage of the array geometry we addressed the following specific issues: (i) detect both the spontaneous and KCl-evoked secretion simultaneously from several chromaffin cells directly cultured on the device surface, (ii) resolve the waveform of different subsets of exocytotic events, and (iii) monitoring quantal secretory events from thin slices of the adrenal gland. The frequency of spontaneous release was low (0.12 and 0.3 Hz, respectively, for adrenal slices and cultured cells) and increased up to 0.9 Hz after stimulation with 30 mM KCl in cultured cells. The spike amplitude as well as rise and decay time were comparable with those measured by carbon fiber microelectrodes and allowed to identify three different subsets of secretory events associated with "full fusion" events, "kiss-and-run" and "kiss-and-stay" exocytosis, confirming that the device has adequate sensitivity and time resolution for real-time recordings. The device offers the significant advantage of shortening the time to collect data by allowing simultaneous recordings from cell populations either in primary cell cultures or in intact tissues.
