ABSTRACT Herein, we demonstrate a simple hydrothermal route to synthesizing ZnSe/ZnO type II heterostructure using L‐cysteine as capping agent. The use of nanomaterials in bioimaging and photocatalysis towards the degradation Azophloxine dye is potential interest. synthesized were characterized by UV–Vis absorption spectroscopy, fluorescence IR scanning electron microscopy, transmission X‐ray diffraction, photoelectron spectroscopy. It exhibits strong sharp emission at 465 nm used an excellent probe for imaging live‐cell bacteria such E. coli S. aureus compared with commercial staining PI (propidium iodide). possess more photo‐stability showed photocatalytic activity azophloxine under sunlight.

Promethazine hydrochloride (PMHC) is a vital drug that used as an anticholinergic, antipsychotic, antihistaminic, analgesic, sedative, and neuroleptic. However, the overdosage of PMHC also causes reproductive variations, cardiac changes, hypotension, endocrinal variations. Hence, detection crucial. Therefore, in this work electrochemical method for reported. The fabrication modified electrode built with tungsten (W), nickel (N), strontium (S) ternary oxide (tWNSO). To best our knowledge, tWNSO preparation reported first time literature. prepared deposited on polypyrrole nanotubes, nanocomposite formed confirmed by various physical characterizations like XRD, SEM, TEM, UV–vis spectroscopy, FTIR DFT studies PMHC. Thus, obtained working fabricated tWNSO/PPyNTs/GCE has effective surface area 0.0436 cm2. Also, no fouling was observed. limit analyte 3.66 nM, quantification 11.10 sensitivity identifying found to be 20.10 μA μM–1 cm–2. effectively detects while demonstrating excellent stability reproducibility.

In this study, facile simultaneous nitrogen (N)-doped zinc tungstate nanorod-decorated N-doped reduced graphene oxide nanosheets (referred to as N-ZnWO4/N-rGO or N-ZWR-x) were prepared by a one-pot hydrothermal method. Here, urea serves structural orienting agent, source of N, and buffer maintain the pH medium throughout synthesis process. The successful formation crystalline nanocomposite was confirmed through X-ray diffraction, Fourier transform infrared spectroscopy, Raman, N2 physisorption, field emission scanning electron microscopy, transmission photoelectron spectroscopy analyses. modified electrode (N-ZWR-1/GCE) also successfully applied for electrochemical detection diphenylamine (DPA). It exhibited dynamic linear range (LR: 0.2–841 μM), limit (LOD: 0.0083 an acceptable sensitivity (SEN: 1.4746 μA μM–1 cm–2) with good stability. This is due its large surface area, mass ionic transport, synergetic effect, chemical Moreover, yields admirable reproducibility, storage stability, selectivity promising electrocatalyst quantify DPA in fresh fruit samples practical analysis.
