Green synthesis of Iron oxide nanoparticles using Lagenaria siceraria and evaluation of its Antimicrobial activity

Abstract

Magnetic iron oxide nanoparticles (MNPs) with appropriate surface chemistry exhibit many interesting properties that can be exploited in a variety of biomedical applications such as magnetic resonance imaging contrast enhancement, tissue repair, hyperthermia, drug delivery and in cell separation. In this study unexplored Lagenaria siceraria leaves extract was found to be capable in green synthesis of Iron oxide nanoparticles (Fe 3 O 4 -NPs) and their characteristics were studied by using UV-visible spectrophotometer, SEM, EDX, XRD, Zeta sizer, and FT-IR. Thus synthesised Fe 3 O 4 -NPs were naturally stabilised, cubic shaped and in the size range of 30 mm -100 nm. The phytochemicals present in the leaf has a main role as reducing agent that assists to the eco friendly synthesis of

Catalytic degradation of methylene blue by iron nanoparticles synthesized using Galinsoga parviflora, Conyza bonariensis and Bidens pilosa leaf extracts

“…This means that the plant extracts will contain different concentrations of natural reducing agents which can influence the characteristics of the nanoparticles. Green synthesized iron oxide nanoparticles from plants offers an alternative for exploitation of plants for pharmaceutical, water treatment, biomedical and catalytic applications [13][14][15][16][17]. Previous studies have shown that iron nanoparticles produced from plants have been used to catalyze the degradation of organic dyes such as bromothymol blue, methylene blue, aniline and Rhodamine B [14,18].…”

“…[14,15] One of the main challenges to prepare the MNPs avoiding the oxidation reaction during the synthesis process using seed, peel, and leaf extract. [10][11][12][13] Moreover, green synthesis reduces the risk of further contamination by decreas-ing the reaction time and maintaining the crystal structure. [16] Hence, the development of MNPs has added much importance to avoid the adverse effects during their applications especially in the biomedical field.…”
