Highly Sensitive Detection

A new supramolecular electrochemical sensor for highly sensitive detection of dopamine (DA) was fabricated based on supramolecular assemblies of mixed two surfactants, tetra-butylammonium bromide (TBABr) and sodium dodecyl sulphate (SDS), on the electrodeposition of gold nanoparticles on graphene oxide modified on glassy carbon electrode (AuNPs/GO/GCE). Self-assembled mixed surfactants (TBABr/SDS) were added into the solution to increase the sensitivity for the detection of DA. All electrodes were characterized by scanning electron microscopy (SEM), cyclic voltammetry (CV), and electrochemical impedance spectroscopy (EIS). The supramolecular electrochemical sensor (TBABr/SDS⋅⋅⋅AuNPs/GO/GCE) showed excellent electrocatalytic activity toward the oxidation of DA. Under the optimum conditions, the concentration of DA was obtained in the range from 0.02 µM to 1.00 µM, with a detection limit of 0.01 µM (3s/b). The results displayed that TBABr/SDS⋅⋅⋅AuNPs/GO/GCE exhibited excellent performance, good sensitivity, and reproducibility. In addition, the proposed supramolecular electrochemical sensor was successfully applied to determine DA in human serum samples with satisfactory recoveries (97.26% to 104.21%).

A green, cost-effective and eco-friendly method for the synthesis of copper oxide nanoparticles (CuO NPs) using Bougainvillea flower aqueous extract at room temperature was reported. The synthesized CuO NPs were characterized by UV–visible spectroscopy, fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM) and X-ray diffraction (XRD) tecniques. The synthesized particles were highly stable, spherical in shape with an average diameter of 12±4 nm. The CuO NPs were explored for their antifungal activity against Aspergillus niger and responses revealed that CuO NPs are highly efficient to inhibit the fungal growth and zone of inhibition were comparable with standard drug. The green route for the synthesis of CuO NPs is suggested in view of promising antifungal activity.
