  Retraction Note: Synthesis of Silver Nanoparticles by Biogenic Methods: Characterization and Development of a Sensor Sensible to Pharmaceutical Medicine Paracetamol (Topics in Catalysis, (2024), 67, 9-12, (585-593), 10.1007/s11244-023-01887-4)

  The Editors-in-Chief have retracted this article because of concerns regarding the validity of the research reported in this work. A review conducted by the journal found that the reported average crystalline size for silver nanoparticles (NPs) as determined by an analysis of the XRD intensity peaks (Fig. 3) is not consistent with the average size determined by TEM imaging (Fig. 4a), and that the former analysis was not adequately reported in the article. Furthermore, there is lack of agreement between the TEM result shown in Fig. 4 and the size distribution of NPs presented in the inset. The authors were asked to comment on these concerns, but their explanation was deemed unsatisfactory. The Editors-in-Chief no longer have confidence in the research presented in this article. The authors disagree with this retraction.

  In this study, silver nanoparticles (Ag NPs) were synthesized in biogenic methods. It is aimed to improve the electrochemical sensor efficiency of synthesized Ag NPs against the pharmaceutical drug paracetamol. For this purpose, fourier transmission infrared spectroscopy (FTIR), ultra-violet visible spectroscopy (Uv–vis), X-ray differentiation (XRD), and transmission electron spectroscopy (TEM) analyses were performed to elucidate the structure of the synthesized Ag NPs. In the TEM characterization results, the mean size of the NPs was found to be 19.035 nm using TEM characterization and the XRD results, the crystalline size of the NPs was 11.66 nm. Sensor studies were performed with cyclic voltammetry (CV) and differential pulse voltammetry (DPV) techniques. Paracetamol showed a sensitivity of approximately 0.4 V to Ag NPs in this study. The linear ranges of this study are 6.5–14.5 µM, with a limit of detection (LOD) of 5.79 µM and a limit of quantification (LOQ) of 17.56 µM.
