Green synthesis of strontium stannate nanorods using extract of Juniperus communis L.: Structural characterization and evaluation of antibacterial, antifungal, and antioxidant activity

Strontium stannate nanorods (SrSnO₃ NRs) were synthesized in the present study via a green, sustainable, and cheap method with leaf extract from Juniperus communis L. UV-visible spectroscopy (UV-Vis), Fourier-transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Field emission scanning electron microscopy (FESEM) with energy-dispersive X-ray analysis (EDAX) were performed to investigate the SrSnO₃ NRs. The particle size distribution (PSD) of SrSnO₃ NRs characterized by using dynamic light scattering (DLS) analysis. The UV-visible spectra of the synthesized SrSnO₃ NRs showed an absorption peak at 279 nm. SEM images confirmed that SrSnO₃ NRs, which have an average size of about 29 nm, include a bunch of rod-like structure. In addition, the as-formed SrSnO₃ NRs demonstrated excellent antibacterial activity against the bacteria Staphylococcus aureus, Enterococcus faecalis, and Escherichia coli. The synthesized SrSnO₃ nanorods also exhibited a significant amount of antioxidant activity. It is also an attractive biocompatible choice for pharmacological and medical applications.
