Green synthesis of iron oxide nanoparticles using Platanus orientalis leaf extract for antifungal activity

Abstract

In this report, aqueous phase green synthesis of iron oxide nanoparticle utilizing Platanus orientalis is elucidated for the first time. The phytoconstituents of the P. orientalis leaf extract serve a dual role as reducing and capping agent during the fabrication of iron oxide nanoparticles. The role of the leaf extract in the synthesis of iron oxide has been briefly demonstrated in this work. The tailored iron oxide particles were characterized using X-ray diffraction, scanning electron microscopy, transmission electron microscopy, energy dispersive X-ray analysis, infrared spectroscopy, ultraviolet-visible spectroscopy, and dynamic light scattering technique. Nonetheless, X-ray diffraction pattern reveals the mixed phase nature of the ensuing iron oxide, i.e. α-Fe2O3 and γ-Fe2O3. The spherical oxide particles have an average diameter of 38 nm as determined from transmission electron microscopy. Infrared spectroscopy results confirmed the stabilization of iron oxide nanoparticles by the phytochemicals present in the leaf extract. Iron oxide nanoparticles show significant antifungal activity against Aspergillus niger and Mucor piriformis, employed as model fungi, but found to be more active toward M. piriformis.

Biogenic synthesis of magnetic iron oxide nanoparticles using inedible borassus flabellifer seed coat: characterization, antimicrobial, antioxidant activity and in vitro cytotoxicity analysis

“…Magnetic nanoparticles show UV absorption band in the range 330 nm-450 nm due to the absorption and scattering of light by the nanoparticles. Similar results were obtained in previous literatures [42,43]. Furthermore, the change in colour of the precursor solution from yellow to black colour during the synthesis process can be attributed to the phenomenon of excitation of Surface Plasmon Resonance [44].…”

Structural characterization, antioxidant and cytotoxic effects of iron nanoparticles synthesized using Asphodelus aestivus Brot. aqueous extract

“…In order to carry out the experiment quartz cuvettes were used. The purpose of UV-vis spectra was to observe the formation of iron nanoparticles [7].…”

“…Let A, A * denote a Leonard pair on V. We can determine whether A, A * is self-dua By [ i= denote a standard ordering of the eigenvalues of A. Then A, A * is self-du is a standard ordering of the eigenvalues of A * (see [7,Proposition 8.7]).…”

“…Iron nanoparticles can be synthesized by different chemical and physical methods such as sol-gel reactions, hydrothermal methods, polyol methods, microemulsion process, radiolysis, aerosol pyrolysis and laser pyrolysis [6]. Recently synthesizing iron oxide nanoparticles using green chemistry attract scientists because of their non toxic and eco friendly properties [7].…”

“…Their usage in biomedical field such as anticancer, antimicrobial, larvicidial, antiplasmodial, targeted drug delivery and cancer therapy are remarkable. Besides, iron nanoparticles are used in lithium ion batteries, high performance CO gas sensors, biosensors and jet printing make use of iron nanoparticles [6,7]. However, in recent years the most prominent features of them are their antitumoral effects [8].…”
