Green Synthesis and Antimicrobial Activity of Senecio glaucus - Mediated Silver Nanoparticles
Silver nano particles (AgNPs) was synthesized using extract of Senecio glaucus extraxt. The effect of extract source on the shape of the Ag nanoparticles and antibacterial activity are investigated. The nature of AgNPs synthesized was analyzed by UV–vis spectroscopy and transmission electron microscope(TEM). Silver nanoparticles were found to have an average size of 15-20 nm and mostly spherical. The antibacterial potential of modified extract containing synthesized AgNPs was compared with that of pure extract by cup plate method. Antibacterial activity of modified plant extract was reported and evaluated against drug resistant of bacterial isolates. Modified shoot extract gives higher response than that of modified root extract which facilitate them as a good alternative therapeutic approach in future. Phytochemical analysis revealed that Senecio glaucus extract act as reducing and stabilizing agent for synthesized silver nanoparticles (AgNPs).
Biosynthesis of silver nanoparticles (AgNPs) by banana leaf extracts was achieved. Plant extracts are not expensive and ecofriendly and thus can be an economic and efficient alternative for the large-scale synthesis of nanoparticles. The AgNPs formed by reaction of banana leaf extracts with aqueous solutions of silver nitrate (AgNO3). The synthesized nano-particles were confirmed by using UV–Vis absorption spectroscopy, X-Ray diffraction (XRD) and Transmission Electron Microscope (TEM). The produced AgNPs has been applied on cotton fabric to impart antimicrobial efficacy by exhaustion method. The treated cotton fabric shows a clear microbial resistance against Staphylococcus aureus, Escherichia coli, and Pseudomonas aeruginosa. The treatments of produced AgNPs on cotton not only improve its antimicrobial efficiency but also influenced the tensile strength of the fabric sample positively. The treatment was found to enhance the color depth and fastness properties of dyed cotton fabric samples.

An environment friendly and wash-durable silver nanoparticle treatment of cotton fabrics was carried out by in situ reduction of silver nitrate using Azadirachta indica leaf extract. The wash durability of the silver nanoparticles treatment on the cotton fabric was improved by pretreating the fabrics by mercerization and by adopting hydrothermal conditions of 120 °C temperature and 15 psi pressure for the in situ synthesis. The silver nanoparticle treated fabrics were characterized using scanning electron microscopy, colorimetric analysis and inductively coupled plasma mass spectroscopy. The coating of silver nanoparticles was seen to be dense and uniform in the scanning electron micrographs of the treated fabrics. An evaluation of the antibacterial efficacy of the silver nanoparticle treated fabric against antibiotic-resistant Gram-positive and Gram-negative strains was carried out. The antibacterial efficacy was found to be the highest against Bacillus licheniformis, showing 93.3%...

Green synthesis is an easy and economical method of synthesizing silver nanoparticles (AgNPs). However, many variables, including the ideal temperature, the volume and concentration of silver nitrate, the amount of plant extract, etc., affect the green synthesis. This article aims to determine the ideal temperature and plant extract amount using the UV-VIS spectrum. It was found above 40 °C was required for both Calendula arvensis (field marigold) leave extract and silver nitrate to synthesize AgNPs. The optimum temperatures were 55 °C and 60 °C for AgNO3 and plant extract, respectively and it was determined using Taguchi orthogonal array based on the UV-VIS spectrum. Silver nanoparticles (AgNPs) can be incorporated into textiles by padding and in-situ methods, but they need accurate plant extract amounts for good antibacterial efficiency. Two equations were proposed for determining the optimum plant extract amount for padding and in-situ methods. Several AgNPs loaded samples were prepared following the derived equations. For evaluating the efficiency of the equations C.reticulata (orange) peel extract was used besides C.arvensis plant extract. The samples were also characterized by antibacterial tests, Scanning Electron Microscope (SEM), Energy Dispersive Spectroscopy (EDS), and X-ray diffraction (XRD). It showed when plant extract was taken according to the equations, around 45 nm nanoparticle size and 100% antibacterial activity were obtained. However, taking 1 ml more plant extract than that of the calculated amount of plant extract increased nanoparticle size to 107 nm and reduced antibacterial activity to 90%.
FABRIC TREATMENT WITH BIOSYNTHETIC SILVER NANO PARTICLES USING PLANT EXTRACT
Transstellar Journals, 2022
Cotton fabric was treated with green synthesized Silver Nano Particles (AgNPs) using a mixture of Neem, Mango and Tulasi extract as a reducing agent in the batch method. Chemical reduction methods were followed for Nano particles formation by adding the extract to Silver nitrate solution in drops. The liquid was then applied to enzymatic pretreated fabric using padding mangle. Both liquid and fabrics samples are characterized using Particle Analyzer (DLS), Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and UV-Spectrophotometer. Average Particle size found 98nm and Zeta Potential was-45 to 55(mV). The purity and crystalline nature of AgNPs were confirmed based on the XRD assessment. In addition, specific functional groups, which led to silver nitrate reduction in AgNP formation, were examined using FTIR. Antibacterial activity assays with Gram Positive and Gram negative demonstrated that AgNPs reduced bacterial growth and produced well-defined inhibition zones.

The aim of this study was to examine the antimicrobial efficiency and color changes of cotton fabrics loaded with colloidal silver nanoparticles which were synthesized without using any stabilizer. The influence of colloidal concentration and consequently, the amount of silver deposited onto the fabric surface, on antimicrobial activity against Gram-negative bacterium Escherichia coli, Gram-positive bacterium Staphylococcus aureus and fungus Candida albicans as well as laundering durability of obtained effects were studied. Although cotton fabrics loaded with silver nanoparticles from 10 ppm colloid exhibited good antimicrobial efficiency, their poor laundering durability indicated that higher concentrated colloids (50 ppm) must be applied for obtaining long-term durability. Additionally, the influence of dyeing with C.I. Direct Red 81 on antimicrobial activity of cotton fabrics loaded with silver nanoparticles as well as the influence of their presence on the color change of dyed fabrics were evaluated. Unlike color change, the antimicrobial efficiency was not affected by the order of dyeing and loading of silver nanoparticles.

Silver nanoparticles have an extremely large specifi c surface area, which increases when in contact with bacteria, viruses, and fungi. This signifi cantly increases their bactericidal activity by decreasing the sizes of silver nanoparticles and by increasing their surface area to volume ratio [15]. According to the literature, the mechanisms of the antimicrobial activity of Ag + and Ag NPs are very similar to each other. Both Ag + and Ag NPs can participate in intermolecular interactions with the cell membrane of bacteria. Furthermore, Ag particles smaller than 10nm have been reported to penetrate into the interior of microorganism cells, where they bind to the thiol groups of enzymes and nucleic acids [16,17].

Silver nanoparticles (AgNPs) presence has considerable impact on microbial growth. In this paper, AgNPs was deposited on surface of four textiles to enhance the anti-microbial properties using immersion technique. Immersion technique was selected since it was simple, no need high energies, and no additional equipment required. In addition, AgNPs was synthesized using in situ-bio technique which is non-toxic, harmless and eco-friendly approach. Four textiles were evaluated, such as TA, TB, TC and TD. The finding projected that antifungal ability was correlated to the type of the textiles. TC textile has the significant antimicrobial activity with 12.33 ± 2.08 of inhibition zone which followed by TD (16.00 ± 3.46), TB (17.67 ± 7.09), and TA (17.67 ± 6.65). In addition, the surface bonding AgNPs on textile was possibility caused by the -OH group. It has a lone pair of electrons on the O atom that can interact with AgNPs to form –OAg bonds.
