“…The authors also demonstrated the removal of iron impurities after functionalization processes and thus the electrocatalytic effect of metals cannot be considered [16]. A similar investigation was performed using MWCNTs of two different lengths (short: 1-5 mm and 30 AE 15 nm diameter; long: 5-20 mm and 30 AE 15 nm diameter) for the adsorptive stripping voltammetric determination of a nitroimidazole derivative; however, this study showed no effect of MWCNT size on the analytical response and sensitivity of this analyte [17].…”

“…The first peak involved four electrons converting the NO 2 group into hydroxylamine, and the second peak was produced by the reduction of hydroxylamine into –NH 2 (Brett et al, 1997 ). 1-Methyl-4-nitro-2-brominemethylimidazole was reduced on a glassy carbon electrode (GCE) modified with multi-walled carbon nanotubes (MWCNTs) using adsorptive stripping voltammetry (AdSV) with a detection limit (DL) and quantification limits (QL) of 4.41 × 10 −6 and 6.21 × 10 −6 mol L −1 , respectively (Jara-Ulloa et al, 2011 ). Wheel-shaped Tb-derived MOF was engineered by Yang et al for the determination of NMZ from aqueous systems using fluorescence spectroscopy.…”

The production of synthetic drugs is considered a huge milestone in the healthcare sector, transforming the overall health, aging, and lifestyle of the general population. Due to the surge in production and consumption, pharmaceutical drugs have emerged as potential environmental pollutants that are toxic with low biodegradability. Traditional chromatographic techniques in practice are time-consuming and expensive, despite good precision. Alternatively, electroanalytical techniques are recently identified to be selective, rapid, sensitive, and easier for drug detection. Metal–organic frameworks (MOFs) are known for their intrinsic porous nature, high surface area, and diversity in structural design that provides credible drug-sensing capacities. Long-term reusability and maintaining chemo-structural integrity are major challenges that are countered by ligand–metal combinations, optimization of synthetic conditions, functionalization, and direct MOFs growth over the electrode surface. Moreover, chemical instability and lower conductivities limited the mass commercialization of MOF-based materials in the fields of biosensing, imaging, drug release, therapeutics, and clinical diagnostics. This review is dedicated to analyzing the various combinations of MOFs used for electrochemical detection of pharmaceutical drugs, comprising antibiotics, analgesics, anticancer, antituberculosis, and veterinary drugs. Furthermore, the relationship between the composition, morphology and structural properties of MOFs with their detection capabilities for each drug species is elucidated.

Crystalline and sphere like morphologies of smaller molecules have many applications. Particle size determination is essentially and important while working with nanomaterials. The information on many physical properties including the size, morphology, surface texture, roughness and chemical composition of materials is the important area of research. Moreover, advanced manipulation of the samples during the SEM experiments can provide key information about the morphology of the crystals at the micro and nanometer scale. The electrochemical reduction of nitro aromatic compound to its amine derivative is of great importance in studying the conductivity and the surface morphology of the cathode. The measurement of the variation of current and electrode potential with time during the electrolysis is also the important area of research. The particle size variation in the reduction product of a nitro aromatic compound increases the biological activity may be due to their particle size. The study of biological activity of the organic molecule before and after electrolysis is an interesting subject in the pharmaceutical industry.
