In this approach, amidol, a toxic organic chemical, is used as a staining developer electrochemically detected by using binary SnO2@Nd2O3 nanocomposites (NCs) by deposition onto a flat glassy carbon electrode (GCE). The NCs were prepared by a wet-chemical process followed by characterization with various conventional techniques, such as the UV-Vis, FTIR, XRD, FESEM, EDS and XPS techniques. During the electrochemical method, the main key points are the sensor analytical parameters, such as selectivity, sensitivity, linearity, concentration variations, validity, response time, and repeatability. The calibration curve was plotted in the full concentration range (FCR) from 0.1 mM to 0.1 nM. From the FCR, the linear dynamic range (LDR) was found in the range 1.0 mM to 0.1 nM. The sensitivity is calculated from the slope of the calibration plot in LDR, which was 158.228 μA μM-1 cm-2. The limit of detection (LOD) and limit of quantification (LOQ) of the fabricated chemical sensor were 0.06 nM and 0.2 nM. respectively. The binary doped NC-based chemical sensor probe is cheap, efficient, and environmentally friendly for detecting unsafe chemicals in the environmental and healthcare fields on a broad scale.
A chemo-enzymatic expeditious route to racemic dihexanoyl (2R*,3R*,4R*)-dehydroxymethylepoxyquinomycin (DHMEQ), the precursor for lipase-catalyzed synthesis of the potent nuclear factor-κB inhibitor, (2 S,3S,4 S )-DHMEQ
