Silver nanoparticles biogenic synthesized using an orange peel extract and their use as an anti-bacterial agent

Abstract

Synthesis of nanoparticles by green methods with antibacterial properties is of great researchers' concern in the explored of new pharmaceutical and biomedical products. In this study, we synthesized a new product of nanosized particles of silver, non-toxic economy, clean, and conservator for energy. An environmentally friendly route is used for synthesizing silver nanoparticles (AgNPs) using an orange peel extract as both reducing and stabilizing agent at room temperature. The synthesized NPs were characterized using ultraviolet (UV)-Vis spectrophotometer, Zitasizer which measures the average size of the particles at about 91 nm, Fourier transform infrared (FT-IR) spectroscopy, scanning electron microscopy (SEM) equipped with the energy dispersive spectroscopy (EDS) and characterization using Transmission electron microscopy (TEM). The results confirmed that the orange peel extract is a very good bioreductant for the synthesis of Ag NPs and we investigated the synthesized nanoparticles as an antibacterial which showed that the biogenic synthesized AgNPs exhibit inhibition, and had significant antibacterial against both gram-positive and gram-negative bacterial strains.

“…This result was comparable to the standard data of JCPDS No. 04–0783 [21] , [22] , [23] , [24] , [25] . The average particle size was calculated by Scherrer equation and was found to be in the range of 20–50 nm.…”

Comparison of the Physical Characteristics of Green-Synthesized and Commercial Silver Nanoparticles: Evaluation of Antimicrobial and Cytotoxic Effects

“…Therefore, previous studies have evaluated banana peels [9], custard apple peels [10], Annona squamosa peel extract [11], Punicagranatum peels [12], Citrus sinensis peel extract [13], and orange peel extract [14] for use in the synthesis of AgNPs. Lakshmipathy et al [15] previously reported the synthesis of palladium nanoparticles using watermelon rind (Citrullus lanatus) powder extract.…”

Biosynthesis of silver nanoparticles using citrus sinensis peel extract and their application as antibacterial agent

“…Therefore green production of Ag-NPs has demonstrated to be more bene icial over other methods, as it is economical and environmentally friendly (Gudikandula and Maringanti, 2016). It does not require adverse conditions like usage of harmful chemi-cals, high pressure and temperature (Bhattarai et al, 2018;Manal et al, 2014). Hence, bio-based synthesis of Ag-NPs has been employed.…”

“…Hence, bio-based synthesis of Ag-NPs has been employed. In green synthesis, the Ag-NPs produced from microbial source are less stable than Ag-NPs produced from the plant source (Manal et al, 2014;Ocsoy et al, 2017). Therefore in the production of Ag-NPs, extract of fruit peel are being utilized.…”
