Green Synthesized Ruthenium Oxide Nanoparticles Mediated through Iris Kashmiriana (Mazar-Graveyard) Plant Extract and Antimicrobial Activity

As per the increasing demand for new sustainable materials and methodologies, green synthesis of metal oxide nanoparticles has drawn the attention of many researchers. However, compared to certain other metal oxides, there has been comparatively less attention towards green synthesis of Ruthenium oxide Nanoparticles (RuNPs). In this paper, RuNPs were synthesized using plant extract of Iris Kashmiriana (found in the high-altitude region of Kashmir in India) and characterized by FT-IR, SEM, EDX, and XRD. Particles were synthesized in the dimensions of 25–30 nm. FT-IR peaks in this 3348 cm-¹ infrared spectrum range confirmed Ru-O symmetric stretching while crystalline structure was confirmed by X-ray diffraction. By displaying a zone of inhibition for erythromycin, the synthesized ruthenium oxide nanoparticles exhibit potent antibacterial action against four different pathogens, including Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, and Streptococcus pneumoniae.
