The Synthesis of silver nanoparticles using Beetroot extract and its antibacterial and catalytic activity

Abstract

Silver nanoparticles (NPs) have been synthesized by aqueous Beetroot extract. Effective parameters on the synthesis of silver NPs like pH, extract volume, silver nitrate concentration and time of reaction have been investigated at room temperature. The synthesized silver NPs have been studied with different analysis like UV-Vis, FT-IR, FE-SEM, TEM, and XRD. Our analysis indicates that the level of Surface Plasmon is 439 nm. The shape of NPs is spherical and the size is 20-30 nm using FE-SEM and TEM technique. Four bacteria (Escherichia coli, Staphylococcus aureus, Bacillus subtilis and Salmonella typhymurium) were used as references bacteria to analyze the antibacterial effect. Antibacterial results show that gram negative bacteria are so sensitive to synthesize silver NP. The recommended method was completely eco-friendly.

Biosynthesis of silver nanoparticle using endophytic fungus (Simpicillium lanosoniveum) isolated from Sargassum wightii and its biological activity

“…The range of the particle size histogram in the current investigation is 20 to 25 nm. This nding rmly established the role of S. lanosoniveum ltrate as a reduction and capping mediatorduring the synthesis of AgNPs.Similar outcomes were reportedon AgNPssynthesized using beetroot extract [39].…”

Microwave-assisted green synthesis of silver nanoparticles using turnip root (Brassica rapa subsp. Rapa) extract and their antibacterial efficacy

“…Moreover, the peak at 2126 cm −1 can be related to the stretching of C=C cm −1 . A significant peak was observed at a frequency of 1260 cm −1 , which can be attributed to the stretching modes of C-N (aromatic amine) [7] and the C-C stretching of alkanes [5]. Other peaks were observed at a frequency of (660, 596, and 557 cm −1 ), which indicate the stretching of the C-Cl group [38].…”

“…Both solutions exhibit a wide band at around 3320 cm −1 , which corresponds to the stretching vibration of the N-H group NH2 (aliphatic primary amine) and the stretching of the OH group in water [35,36]. Another signal seen at 1640 cm −1 suggests the existence of a double bond, perhaps attributed to the stretching of a C=C group (conjugated alkene) and carbonyl vibration in the amide bond [7,36,37]. Moreover, the peak at 2126 cm −1 can be related to the stretching of C=C cm −1 .…”

“…Factors, such as low toxicity, cost-effectiveness, high yield, and biocompatibility are of great importance. Furthermore, the size of the produced nanoparticles can be readily regulated through the manipulation of factors such as pH, temperature, and concentration [6][7][8]. Moreover, modern studies have consistently demonstrated that the use of microwaves aids in plant extraction and enhances production.…”
