A novel ecofriendly electrochemical sensor for in-situ detection of testosterone based on gold nanoparticles (AuNPs) and a semi-amorphous metal organic framework (MOF) has been developed clinical diagnosis doping control. For this purpose, MIL-100(Fe) synthetized according to green path with crystallization times tuned in the range 2–24 h. The platform was constructed via drop-casting MOF AuNPs onto graphene (GPH) screen-printed electrode (SPE) surface. surface structure morphology properties unmodified modified electrodes were investigated by (SEM), energy-dispersive X-ray spectroscopy analysis (EDX), photoelectron (XPS), Raman spectroscopy, cyclic voltammetry (CV) impedance (EIS), demonstrating enhanced response obtained shorter time 2 h (MOF2h) AuNPs, compared electrode. AuNPs/MOF2h/GPH/SPE responsive nanomolar concentrations testosterone, showing wide linear from 1 50 nM limit (LOD) 0.5 nM, which correlates serum concentration values healthy males. combination these results excellent performance maintained proposed when interfaced miniaturized potentiostat (Sensit-Smart) directly connected smartphone, highlights potential device towards sensing, particular medical

The current study's objective was to develop a ZnO photocatalyst for the treatment of reactive blue 19 (RB19) from textile wastewater by depositing nanostructures over nanoporous anodized aluminum oxide (ZnO-AAO). ZnO-AAO membrane created using atomic layer deposition (ALD) technique. SEM, XRD, and EDS morphological structural characterizations demonstrated that were successfully deposited on AAO membrane. Studying optical properties revealed band gap energies ZnO, AAO, membranes found be 3.19, 2.85, 2.92 eV, respectively. This resulted in an improvement separation efficiency photo-excited electrons holes as well increase photocatalytic activity sample visible light region. electrochemical parameters had lowest charge transfer resistance, which indicates photoinduced contacts effectively have slower recombination rates. According research performance, photocatalysts required 70 90 minutes exposure completely decolorize RB19, decolorization RB19 actual showed dye could removed means when present.
