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.

Detecting multiple tumor markers is of great importance. It helps in early cancer detection, accurate diagnosis, and monitoring treatment. In this work, gold nanoparticles–toluidine blue–graphene oxide (AuNPs-TB–GO) nanoparticles–carboxyl ferrocene–tungsten disulfide (AuNPs–FMC–WS2) nanocomposites were prepared for labeling Carcinoembryonic antigen (CEA) antibody Carbohydrate 72–4 (CA72-4) antibody, respectively, used as two kinds probes with different electrochemical signals. With the excellent magnetic performance biotin immune beads (IMBs), biofunctional IMBs firmly deposited on glassy carbon electrode (MGCE) surface by applying a constant field, then CEA CA72-4 immobilized avidin–biotin conjugation. The assay was based change detection peak current. Under optimum experimental conditions, linear range two-component immunosensor from 0.01 to 120 ng/mL, low limit 0.003 0.05 35 U/mL, 0.016 U/mL. results showed that proposed enabled simultaneous exhibited good reproducibility, high selectivity, sensitivity. particular, multiplexed immunoassay approach does not require sophisticated fabrication well-suited high-throughput biosensing application other areas.
