Synthesis of silver nanoparticles using Peganum harmala extract as a green route

Abstract

In this study, we investigated the synthesis of silver nanoparticles using Peganum harmala water extract at ambient temperature. The Ag nanoparticles (AgNPs) were characterized by ultravioletvisible spectroscopy (UV-vis), Fourier transform infrared spectroscopy (FT-IR), powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and transmission electron microscopy (TEM). The average particle size of the silver nanoparticles was about 23 nm. Inhibitory activity of the synthesized AgNPs was tested against human pathogens like Escherichia coli and Staphylococcus aureus. The results indicated that the AgNPs showed moderate inhibitory actions, demonstrating its antibacterial value against pathogenic diseases. ARTICLE HISTORY

Flacourtia indica based biogenic nanoparticles: development, characterization, and bioactivity against wound associated pathogens

“…Moreover, the antibacterial effects of the FI-AgNPs are owing to the interaction of AgNPs with the three-dimensional microbial structure of the cell walls of bacteria. The destruction of the bacterial cell wall may also be attributed to the release of ROS (reactive oxygen species) that can damage membrane protein and nucleic acid [52,53]. Bagherzadeh et al [54] compared the antibacterial effects of biosynthesized AgNPs prepared using saffron extract and market purchased AgNPs and showed that the extract of the saffron plant and purchased AgNPs did not show enough antibacterial effects but biosynthesized AgNPs exhibited promising antibacterial activity.…”

Biosynthesis of silver nanocomposite with Tarragon leaf extract and assessment of antibacterial activity

“…After incubation at 65 °C for 2 h, the dried powder of Ag-MMT-NPs was collected for further characterization [28]. In other previous similar investigations, the maximum volume used for synthesis of AgNPs has been 50 mL [18], but in our work the volume was increased to 2000 cc which resulted in synthesizing 2 g of silver nanoparticles. due to this information, we can claim that this method could be easily adopted for large-scale synthesis of NPs.…”

“…The absorption band at 3396.66/cm in the spectrum might be attributed to the stretching vibrations of secondary amines of N-H bond and bonded hydroxyl (-OH) groups of phenols and carboxylic acids [18]. Bonded hydroxyl (-OH) groups of carboxylic acids and phenols could produce absorption bands at 3396.66/cm (Fig.…”

“…AgNP synthesis has been evaluated in different extracts, including Medicago sativa [13], Ulva flexuosa [14], Achillea biebersteinii [15], Moringa oleifera [16], Calendula officinalis [17], Peganum harmala [18], Green Tea [19], Pistacia atlantica [20], olive [21], Aloe vera [22], and Coriandrum Sativum [23]. We developed a simple, rapid, and green method to synthesize AgNPs, using MMT and Tarragon leaf extract as both a reducing and capping agent under normal atmospheric conditions in the batch method in this study.…”

“…The scrutiny of the literature revealed some notable plant extract used for facile synthesis of AgNPs. For example, Nervalia zeylanica [31], Beutia monosperma [32], Leucaena leucocephala L. [18], Ipomoea digitata [33], Caesalpinia pulcherrima [34], Buddleja globosa [35], Sacha inchi [36], Peganum harmala [37], unripe fruit of Annona reticulata [38], Ziziphora tenuior [39], Caralluma fimbriata [40], root of Acanthospermum hispidum [41], Pistacia atlantica [42] and Rosa Chinensis L. [43] has been already reported.…”
