“…48−52 Compared to these methods, the LOD value of the novel CUPRAC−GDH-based biosensor was generally found to be close to or even lower than the values reported in some of these studies. It is seen that the LOD value of the GDH−CUPRACbased biosensor was also found to be lower than those of biosensors based on ABTS, 53,54 I 2 -starch, 55 o-dianisidine, 56 FeSCN 2+ including Fenton reaction, 57 and CUPRAC 41 reagents, which is quite similar to our study but using the GOx enzyme. Moreover, the LOD value of the GOx-based glucose biosensor is lower than or comparable with those of other strategies based on etching 58,59 or formation 60 of plasmonic metal nanoparticles.…”

This study describes a novel optical glucose biosensor based on a colorimetric reaction between reduced nicotinamide adenine dinucleotide (NADH) and a copper(II) neocuproine complex ([Cu(Nc) 2 ] 2+ ) as a chromogenic oxidant. An enzymatic reaction takes place between glucose and glucose dehydrogenase (GDH)–chitosan (CS) immobilized on silanized magnetite nanoparticles (CS@SiO 2 @Fe 3 O 4 ) in the presence of coenzyme NAD + . The oxidation of glucose to gluconolactone via the immobilized enzyme is coupled with the reduction of NAD + to NADH at the same time. After the separation of GDH-immobilized SiO 2 @Fe 3 O 4 with a magnet, the enzymatically produced NADH chemically reduces the chromogenic oxidant cupric neocuproine to the cuprous chelate. Thus, the glucose biosensor is fabricated based on the measurement of the absorbance of the formed yellow-orange complex ([Cu(Nc) 2 ] + ) at 450 nm. The obtained results show that the colorimetric biosensor has a wide linear response range for glucose, between 1.0 and 150.0 μM under optimized conditions. The limit of detection and limit of quantification were found to be 0.31 and 1.02 μM, respectively. The selectivity properties of the fabricated biosensor were tested with various interfering species. This biosensor was applied to various samples, and the obtained results suggest that the fabricated optical biosensor can be successfully used for the selective and sensitive determination of glucose in real samples.

“…For nonionic surfactants, cloud point (CP) is the most important physical parameter. An extensive literature survey finds that alcohols can have an impact on clouding development. , The nonionic surfactant Triton X-114 (TX-114) is widely used commercially. − The micellar properties of the Triton X family mainly depend on the oxyethylene unit (EO). The length of the polar (EO) n headgroup (where n denotes the number of oxyethylene units) influences strongly the micellar properties .…”

The influence of 2,2,2-trifluoroethanol (TFE) on the micellar properties of ionic surfactants hexadecyltrimethylammonium bromide (CTAB), hexadecyltrimethylammonium ptoluenesulfonate (CTAT), sodium dodecyl sulfate (SDS), Nlauroylsarcosine sodium salt (SDDS), and nonionic surfactant Triton X-114 (TX-114) in aqueous solutions was studied using tensiometry, electrical conductivity, fluorimetry, time-resolved fluorescence, and microcalorimetry. With increasing concentrations of TFE, the micellar charge densities of the ionic head groups decrease, causing a decrease in the critical micelle concentration (CMC) of ionic-surfactant solutions (SDS, SDDS, CTAB, and CTAT) in micellar solutions. However, for nonionic surfactant TX-114, the polar headgroup undergoes some conformational changes causing an increase in the value of CMC. Time-resolved fluorescence decay measurements were done to get evidence of penetration of TFE molecules into the stern layer of the micelle. The micellar aggregation number declines with increasing concentration of solvent, indicating a higher concentration of mixed solvent reducing the number of monomers needed for micellization for ionic surfactants, whereas for nonionic TX-114, it indicates some structural changes of the molecule forming the micelle in the presence of TFE.

Material-specific electrocatalytic activity and electrode design are essential factors in evaluating the performance of electrochemical sensors. Herein, the technique described involves electrospinning manganese-based metal–organic frameworks (Mn-MOFs) to develop MnO x nanostructures embedded in carbon nanofibers. The resulting structure features an electrocatalytic material for an enzyme-free glucose sensor. The elemental composition, morphology, and microstructure of the fabricated electrodes materials were characterized by using energy-dispersive X-ray spectroscopy (EDX), field-emission scanning electron microscopy (FESEM), and transmission electron microscopy (TEM). Cyclic voltammetry (CV) and amperometric i–t (current–time) techniques are characteristically employed to assess the electrochemical performance of materials. The MOF MnO x -CNFs nanostructures significantly improve detection performance for nonenzymatic amperometric glucose sensors, including a broad linear range (0 mM to 9.1 mM), high sensitivity (4080.6 μA mM–1 cm–2), a low detection limit (0.3 μM, S/N = 3), acceptable selectivity, outstanding reproducibility, and stability. The strategy of metal and metal oxide-integrated CNF nanostructures based on MOFs opens interesting possibilities for the development of high-performance electrochemical sensors.
