| Özet |
| In this paper, a novel electrochemical sensing platform has been developed based on the electrodes modified with heteroaromatic molecules decorated with gold nanoparticles (AuNPs). For this purpose, the GC electrodes were first covered with pyridine and phenanthroline rings by using diazonium reduction method. Then, the formation of AuNPs was achieved via the electrochemical reduction of AuCl4− ions preadsorbed to the modified GC surfaces. The AuNPs, for comparison, were also prepared on polyphenylene films (PPh) obtained by electrochemical reduction of in situ generated benzenediazonium salts. The existence of the nanoparticles was confirmed by using spectroscopic and electrochemical techniques such as scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), X-ray diffraction (XRD), and cyclic voltammetry. The results have shown that the homogeneity of particle … |
