Here, we are intended to present a simple and facile synthesis of novel orange emitting thiazole-pyridone fluorescent tag (TPFT) by a simple diazo coupling reaction and the structural elucidation was carried out by IR, NMR (¹H and ¹³C), UV–Vis, photoluminescence and HR-MS spectrometry. The solvatochromic behaviour of the TPFT offered crucial information about the formation of hydrazone and azo tautomeric forms.

Comprehensive LFP visualization is revealed under both normal and UV light conditions (365 nm). The cyclic voltammetry (CV) and differential pulse voltammetry (DPV) were used to analyse the electrochemical behaviour of the TPFT-modified glassy carbon electrode (MGCE) and exhibited a lower detection limit of 7.89 × 10⁻⁸ M (S/<i>N</i> = 3) with a linear range of 0.5–8.0 μM for DA detection.

This work focused on the generation of ZnO NPs using the peel of <i>Cucumis melo</i> fruit. The NPs were then analyzed and characterized using UV–Vis spectroscopy. The results indicated that at a wavelength of 352 nm, it was proven that the biosynthesis of ZnO NPs had occurred. The XRD pattern indicated the presence of dense crystal structures.
