Role of Ribes khorassanicum in the biosynthesis of AgNPs and their antibacterial properties

Abstract

Silver nanoparticles (AgNPs) have been biosynthesised through the extracts of Ribes khorassanicum fruits, which served as the reducing agents and capping agents. Biosynthesised AgNPs have been found to be ultraviolet-visible (UV-vis) absorption spectra since they have displayed one surface plasmon resonance peak at 438 nm, attesting the formation of spherical NPs. These particles have been characterised by UV-vis, field-emission scanning electron microscopy, energydispersive X-ray spectroscopy, X-ray diffraction, Fourier transform infrared spectroscopy, and transmission electron microscopy analysis. The formation of AgNPs at 1.0 mM concentration of AgNO 3 has resulted in NPs that contained mean diameters in a range of 20-40 nm. The green-synthesised AgNPs have demonstrated high antibacterial effect against pathogenic bacteria (i.e. Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa). Biosynthesising metal NPs through plant extracts can serve as the facile and eco-friendly alternative for chemical and/or physical methods that are utilised for large-scale nanometal fabrication in various medical and industrial applications.

Bioinspired Green Synthesis of Silver Nanoparticles Using Three Plant Extracts and Their Antibacterial Activity against Rice Bacterial Leaf Blight Pathogen Xanthomonas oryzae pv. oryzae

“…The FTIR results showed terpenoids, phenolic compounds, and flavonoids could be used as capping agents and stabilizers to synthesize AgNPs. Our study proved the FTIR results of Taghavizadeh et al [ 45 ].…”

Assessment of Antioxidant and Antimicrobial Activities of Silver Nanoparticles Biosynthesized by Haplophyllum Obtusifolium

“…In another study by Taghavizadeh Yazdi et al, AgNPs were fabricated with an approximate size of 11 nm using Helichrysum extract, which were effective against various species of pathogenic bacteria (5). The capability of AgNPs in preventing bacterial cell growth can be in part related to their small size and large surface area, providing adequate contact interface with bacteria (27,(32)(33)(34). It has been stated that bacteria death could be due to the great leakage of their macromolecules (35).…”

Silver‐coated copper nanocomposites synthesis using the essence of Foeniculum vulgare mill and estimation of its antibacterial and cytotoxicity effects

“…Silver (Ag) or its compounds are known to have excellent antibacterial attributes properties that were implemented in medicine in the distant past [26][27][28]. It has found its way into many industries due to its strong antibacterial properties in low doses [29][30][31][32].…”
