“…The poor electrochemical properties of NDC at high pH might have been due to poor solubility of KCZ at such pH levels. Though higher pH (9.42) of NH 3 −NH 4 Cl buffer showed higher solubility and higher electrochemical signal , but interestingly in our experimental conditions, both the solubility and reversibility were improved at lower pH (≤4). Due to the good solubility, quasireversibility, and enhanced electrochemical signal at pH 3, this pH was used for the rest of the studies.…”

“…As a cost‐effective, reliable and quantitative detection methodology, electrochemical analysis has already proven its excellence. Thus, since the completion of investigations of the electrochemical properties of KCZ , various electrodes such as mercury electrodes , silver solid amalgam electrodes , boron‐doped diamond electrodes , boron‐doped diamond electrodes using square wave adsorptive voltammetry , GCEs , and CPEs have been used to develop KCZ sensors. To obtain better electrochemical sensing performances, the bulk electrodes have been modified with various electrocatalysts such as MWCNTs , AuNPs , and β‐cyclodextrin .…”

In this study, the electrocatalytic characteristics of nitrogen‐doped carbon (NDC) prepared from Clerodendrum Infortunatum L leaves on a glassy carbon electrode (GCE) surface was evaluated with regards to its ability to detect the electroactive drug ketoconazole (KCZ). The NDC was prepared by carrying out a simple pyrolysis of dry powder of the leaves at 850 °C. The prepared NDC was characterized using field‐emission scanning electron microscopy, energy dispersive spectroscopy, transmission electron microscopy, X‐ray photoelectron spectroscopy and Brunauer‐Emmett‐Teller analysis, and was then used as an electrode material. The performance of the electrochemical KCZ sensor with the NDC‐modified glassy carbon electrode (NDC/GCE) was found to be optimal when using PBS buffer at pH 3 and a concentration of 0.1 mg/ml of NDC in the conjugate with Nafion polymer. Under these conditions, the NDC/GCE displayed a KCZ detection limit of 3 μM and a linear dependence of its response on KCZ concentration over a wide range of KCZ concentrations from 47 μM to 752 μM (R2=0.9742). These results confirmed the potential of NDC as an electrocatalyst.

“…Ketoconazole and ciclopiroxolamine are synthetic, highly effective broad‐spectrum antifungal agents. Mielech‐Łukasiewicz and Roginska used BDD electrodes to quantify these pharmaceuticals by SWV methodology. BDD electrodes were cathodic conditioned from cycling from −2.9 V to 0.3 V (vs. saturated calomel electrode) at 500 mV s −1 .…”

diamond (BDD) electrodes possess outstanding physical, chemical, and electronic properties and have been successfully, yet in a limited way, explored in the electroanalysis of substances with therapeutic action (analgesics, antipyretics, antibiotics, anti-inflammatories, antihypertensives, antidepressants, vitamins, and others) in diverse milieus (pharmaceutical formulations, urine, serum, whole blood, surface waters, seawaters, groundwater, wastewaters, etc.). Therefore, in this Review, a broad overview of the available scientific information on recent progress and achievements of the application of bare or modified BDD electrodes to the bioanalytical and environmental detection of pharmaceutical compounds is presented. The main parameters, for example boron concentration, applied operational conditions during pretreatment, chemical and physical structure, and other influential factors on the electroanalytical BDD electrodes performance, are discussed.[a] Dr.

The widespread applications of cosmetics in modern life make their analysis particularly important from a safety point of view. There is a wide variety of restricted ingredients and prohibited substances that primarily influence the safety of cosmetics. Sample preparation for cosmetic analysis is a crucial step as the complex matrices may seriously interfere with the determination of target analytes. In this review, some new developments (2010-2016) in sample preparation techniques for cosmetic analysis, including liquid-phase microextraction, solid-phase microextraction, matrix solid-phase dispersion, pressurized liquid extraction, cloud point extraction, ultrasound-assisted extraction, and microwave digestion, are presented. Furthermore, the research and progress in sample preparation techniques and their applications in the separation and purification of allowed ingredients and prohibited substances are reviewed.
