Nanocrystalline-diamond (NCD) films have been utilised for the detection of penicillin G for the first time. The developed penicillin-sensitive biosensor consists of a field-effect capacitive electrolyte-diamond-insulator-semiconductor (EDIS) structure with an immobilised enzyme layer that covers the gate region of the sensor. Undoped NCD thin films of about 100 nm thickness were grown on a p-Si-SiO 2 (50 nm thermally grown SiO 2 ) structure by microwave plasma-enhanced chemical vapour deposition. The enzyme penicillinase has been adsorptively immobilised directly onto the O-terminated NCD surface. The EDIS biosensors have been characterised in buffer solutions with different content of penicillin G by means of capacitance-voltage and constantcapacitance method. The developed penicillin biosensor possesses a low detection limit of 5 µM and a high sensitivity of 60-70 mV/decade in a wide linear range of 0.005-2.5 mM penicillin G concentration.

In this work, a boron-doped diamond (BDD) electrode was used for the electroanalytical determination of indole-3-acetic acid (IAA) phytohormone by square-wave voltammetry. IAA yielded a well-defined voltammetric response at + 0.93 V (vs. Ag/AgCl) in Britton-Robinson buffer, pH 2.0. The process could be used to determine IAA in the concentration range of 5.0 to 50.0 mM (n = 8, r = 0.997), with a detection limit of 1.22 mM. The relative standard deviation of ten measurements was 2.09 % for 20.0 mM IAA. As an example, the practical applicability of BDD electrode was tested with the measurement of IAA in some plant seeds.

“…Boron doped diamond (BDD) electrodes have been extensively used in recent years in electrosynthesis, electroanalysis, electrochemical combustion, and as electrocatalyst supports [31][32][33], as they offer a number of advantages over traditionally employed electrodes. Furthermore, BDD electrodes are particularly attractive for electrochemical applications due to their high corrosion resistance, the very wide electrochemical window in aqueous solutions, low and stable background current, low sensitivity to dissolved oxygen, slight adsorption of polar molecules, long-term response stability and excellent activity towards any redox analytes [34][35][36][37].…”

In the present paper, a sensitive electroanalytical methodology for the determination of capsaicin using adsorptive stripping voltammetry (AdSV) at a boron-doped diamond (BDD) electrode is presented. The voltammetric results indicate that in the presence of sodium dodecylsulfate (SDS) the BDD electrode remarkably enhances the oxidation of capsaicin which leads to an improvement of the peak current with a shift of the peak potential to less negative values. A linear working range of 0.05 to 6.0 mg mL À1 (0.16-20 mM) with a detection limit of 0.012 mg mL À1(0.034 mM) has been obtained using BDD electrode by AdSV.
