Zinc has been demonstrated to boost immune response during SAR-CoV-2 infection, where it prevents coronavirus multiplication. Clinical investigations have testified its beneficial effects on respiratory health and deficiency may reduce function. A highly sensitive detection of Zn(II) ion via differential pulse voltammetry (DPV) utilizing an environmentally friendly modified screen-printed carbon electrode (SPCE) electrochemically reduced graphene oxide (ErGO) embedded with carboxylated-8-carboxamidoquinoline (CACQ) as chelating ligand. The green CACQ/ErGO-modified SPCE was characterized by spectroscopy techniques, such Fourier-transform infrared (FTIR) spectroscopy, Raman field-emission scanning electron microscopy energy dispersive X-ray (FESEM-EDX). electrode-solution interface studied electrochemical cyclic (CV) DPV methods. CACQ-modified wrinkled ErGO conferred a large surface-to-volume ratio multiple binding sites resulting in greater opportunity for dative covalent events coordination chemistry, considerably accelerated the transfer rate at surface. sensor quick time (60 s), broad linear range [1 pM-1 μM ion], limit (LOD) 0.53 pM, 35 days storage period (≥80% initial retained), good reproducibility [relative standard deviation (RSD) = 3.4%], repeatability (RSD 4.4%). developed applied determine concentration dietary supplement samples, results were agreement those obtained from inductively coupled plasma-mass spectrometry (ICP-MS).
