“…9,10 The pharmaceutical industry has begun utilising BDD electrodes for electroanalysis, which can be used to successfully detect a diverse range of biological molecules including caffeine, 11 glucose, 12 organic acids, 13 serotonin and histamine, 14 purines, 15 and even cofactors such as nicotinamide adenine dinucleotide. 16,17 BDD electrodes can also be used for water treatment and purification, 18 for detecting trace amounts of contaminants in water via anodic stripping voltammetry, 19 electrosynthesis of organic 20 and inorganic 21 compounds, neural interfacing, 22,23 and the fabrication of supercapacitors. 24 The performance of BDD electrodes can often be greatly improved by modifying their size, shape and surface structure.…”

“…The presence of a sharp and strong band at 592-588 cm −1 indicates the presence of Fe-O stretching vibrations. This indicates the formation of polymer composites [36]. The FTIR spectrum of Fe 2 O 3 is shown in Figure 3b, with characteristic peaks originating from the Fe-O vibration in the range of 400-600 cm −1 .…”

Abstract:In the present study, a new biosensor based on lipase from Candida rugosa (CRL) was developed for amlodipine besylate drug (AMD) with biodegradable material using a mixture of polyaniline iron oxide and gelatin. Polyaniline/Fe 2 O 3 (PANI@Fe 2 O 3 ) was prepared by a chemical polymerization method in a medium of ammonium persulfate as an oxidant and characterized by employing Scanning Electron Microscopy (SEM), Fourier Transform Infrared (FTIR), and Ultra-violet (UV) spectroscopy. The purified enzyme was entrapped in the biocomposite matrix film with the aid of a glutaraldehyde cross-linking reagent to establish the immobilization of the lipase. The principle of the biosensor is based on the electrochemical properties of amlodipine besylate (AMD), which were studied for the first time using the cyclic voltammetric method. The cathodic behavior of AMD was measured on the irreversible reduction signal at −0.185 V versus Ag/AgCl at pH 7.4 and 30 • C in a phosphate alkaline buffer.

“…The recovery values were in the range of 94 % and 106 %. Similarly, Mansano and coauthors using different SWV methodologies to simultaneous detection of: AML and VAL or AML, VAL and HCTZ and Pereira Silva and coauthors quantified HCTZ and AML also using SWV methodology . In addition, there are methodologies developed by other research groups for the simultaneous detection of AML with atenolol, and with atorvastatin …”

Electroanalysis of Pharmaceuticals on Boron‐Doped Diamond Electrodes: A Review

et al. 2019

View full text Add to dashboard Cite

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.
