Potential Antifungal and Antimicrobial Effects of Nano Zinc Oxide Particles Obtained from <i>Cymbogobon citratus</i> Leaf Extract Using Green Technology

Abstract

Nanoparticles obtained from physical and chemical methods are uniformly sized having long term stabilities. However, their syntheses usually involve expensive chemicals which are toxic, carcinogenic and require high temperature and pressure. These issues can be addressed by facile and eco-friendly green synthesis. This study focuses on to synthesis of zinc oxide nanoparticles (ZnO NPs) using Cymbogobon Citratus aqueous extract with zinc acetate. The prepared particles were calcined at 450 o C. The synthesized NPs were categorized using FTIR, UV-Visible, XRD and SEM techniques. FTIR verified zinc oxide vibrational frequency at 551 cm -1 . UV-Visible spectrum displayed the ZnO absorption peak at λ max of 370 nm. XRD studies showed average particle size about 4.96 nm much smaller as compared to most of the ZnO NPs reported earlier. SEM image demonstrated crystalline and porous nano-sheets for the prepared NPs. These NPs were also evaluated against Staphylococcus aureus, Escherichia coli, Salmonella typhi, Microsporum cannis, Aspergillus flavus and Fusarium

“…This is because the number of atoms, ions, or molecules that make up a nanoparticle increases on its surface rather than within it. Nanotechnology is the study of microscopic structures with sizes between 0.1 and 100 nm [1,2]. As a result, different nanoparticles with specific traits arise, and the nanoparticles display diverse chemical, physical, and biological attributes at the nanoscale compared to their respective particles at larger sizes.…”

“…Currently, plant-mediated synthesis of NPs has attracted the attention of researchers due to its costeffectiveness, sustainability, and useful applications [27,28]. Plants have been considered important sources for green syntehsis due to their easy availability [29] and useful phytochemical ingredients [30,31].…”
