This book was released on 2018-06-13 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoparticles are particles with dimension on the range 10-9 and 10-10. Green synthesis is the new method developed for the synthesis of nanoparticles which is small in size, large surface area and eco-friendly. In India plant and tree leafs are used as medicine for the treatment of various diseases. They are rich source of antimicrobial agents. Silver, copper and zinc nanoparticles are synthesised from the leaf extract of different plants. Leaf extracts of Glycosmis pentaphylla (Pannal), Macaranga peltata (Vatta), Emilia sonchifolia (Muyal cheviyan), Tabernaemontana divericata (Nandhiar vattam) and Clerodendrum infortunatum (Peravam) are used for the synthesis of nanoparticles. Leaf extract is added to the prepared stock solution of1mM silver nitrate, 100mM copper sulphate and100mM zinc sulphate. Synthesised nanoparticles were characterized by UV-VIS spectrophotometry to confirm the formation of nanoparticles. Anti-bacterial are used to treats bacterial infections. The leaf extract and silver nitrate, copper sulphate, zinc sulphate has antibacterial activity. The antibacterial activity of synthesised nanoparticle is determined using agar well diffusion method. The synthesised nanoparticles exhibit anti- bacterial activity by inhibiting the growth of gram negative and gram positive bacteria.

Book Synopsis Green synthesis of copper and zinc nanoparticles from plant extracts and evaluation of their antifungal activity against Fusarium oxysporum cubense: an overview by : Prem Jose Vazhacharickal
Download or read book Green synthesis of copper and zinc nanoparticles from plant extracts and evaluation of their antifungal activity against Fusarium oxysporum cubense: an overview written by Prem Jose Vazhacharickal and published by Amazon Publishers, USA. This book was released on 2019-04-20 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Soil borne diseases which are caused to various plants include a wide variety of soil microbes like fungi and bacteria, among which Fusarium wilt is one such disease caused by Fusarium oxysporum cubense in banana plants. Wilt disease or the panama disease of plant is among the most destructive disease of banana in the tropics and even the control methods like field sanitation, soil treatments and crop rotations have not been a long term control for this disease. An alternative method of treating Fusarium oxysporum was adopted by using various natural plant leaves of Chromolaena odorata, Justicia adhatoda, Glycosmis pentaphylla, Azadirachta indica, Gliricidia sepium, Piper nigrum, Ocimum tenuiflorum and Tabernaemontana divaricate. Nanoparticles are small particles with a dimension of 10-9 and 10-10. Green synthesis is a new method developed for the synthesis of nanoparticles which is small in size, large surface area and eco- friendly. Leaf extracts of these plants were used for synthesis of copper and zinc nanoparticles, as nanoparticles are powerful antimicrobial agents. The extract is prepared with a stock solution of 100mM copper sulphate and 100mM zinc sulphate. The leaf extracts were prepared with 5 solvents (Distilled water, Propane, Hexane, Acetone and Methanol). The action of plant leaves were observed by the zone of inhibition obtained with a concentration of 50, 100 and 150µl respectively. The result was more in copper nanoparticles of leaf extract as compared to the zinc nanoparticles of particular leaf extracts but the zinc particles with methanol and propane showed good result with particular leaves. In dried condition of leaves copper nanoparticles with propane as solvent exhibited a greater zone of inhibition. Moreover the solvent, methanol showed good results with both zinc and copper nanoparticles. The synthesized nanoparticle were characterized by UV-VIS spectrophotometry to confirm the formation of nanoparticles. Green synthesis is used namely because of low cost, simple, use of less toxic materials, most important is eco-friendly.
Book Synopsis Synthesis of silver, copper and zinc nanoparticles from Carica papaya, Annona muricata, Passiflora edulis, Cycas circinalis, Pouteria campechiana seeds and evaluation of their antibacterial activity by : Prem Jose Vazhacharickal
Download or read book Synthesis of silver, copper and zinc nanoparticles from Carica papaya, Annona muricata, Passiflora edulis, Cycas circinalis, Pouteria campechiana seeds and evaluation of their antibacterial activity written by Prem Jose Vazhacharickal and published by Prem Jose. This book was released on 2018-06-13 with total page 74 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is an emerging field of science. It has increased applications in diverse area for the development of new materials at nanoscale levels. Synthesis of nanoparticles using biological methods is referred as greener synthesis of nanoparticles. Seed extracts of papaya (Carica papaya), Mullatha (Annona muricata), Passion fruit (Passiflora edulis), Eenth (Cycas circinalis), Egg fruit (Pouteria campechiana) are used for the synthesis of silver, copper, and zinc nanoparticles. These plants have medicinal as well as antibacterial activity. Nanoparticles prepared from these seed extracts have antibacterial activity. Synthesized nanoparticles were characterized by UV-VIS Spectrophotometry. Silver nanoparticles shows maximum peak at 385 nm. Copper nanoparticles shows maximum peak at 680 nm. Zinc nanoparticles shows maximum peak at 350 nm. Synthesized silver, copper and zinc nanoparticles shows antibacterial activity against Salmonella species, Pseudomonas species, Staphylococcus species, E. coli and Klebsiella species. Antimicrobial assay was performed by agar well diffusion method using Muller Hinton agar media. when antibacterial activity of silver, copper and zinc nanoparticles from 3 different concentrations were observed, nanoparticles have 60 µl concentration shows maximum activity against these microbes. Silver nanoparticles shows greater antibacterial activity compared to silver nitrate and seed extract. Copper nanoparticles shows greater antibacterial activity compared to copper Sulphate and seed extract. Zinc nanoparticles shows greater antibacterial activity compared to zinc Sulphate and seed extract. Maximum zone of inhibition was at 60 µl for all the bacterial cultures. This green synthesis method is alternative to chemical method, since it is cheap, pollutant free and eco-friendly.

Download or read book Green Synthesis of Silver Nanomaterials written by Kamel A. Abd-Elsalam and published by Elsevier. This book was released on 2021-10-28 with total page 798 pages. Available in PDF, EPUB and Kindle. Book excerpt: Green Synthesis of Silver Nanomaterials illustrates how to biologically scale up silver nanoparticle synthesis. This book covers green synthesis of silver nanomaterials, via plants, agricultural waste, fungi, and microorganisms. Sections cover the synthesis and characterization of chemical and green synthesis, various types of silver nanomaterialism, the ability of different fungal species, such as filamentous fungi, to produce silver nanoparticles, the microbial synthesis of silver NMs, biosynthesis mechanisms, toxicity, fate and commercialization. As examples, greener pathways and mechanisms, toxicity of silver nanoparticles in aquatic life and in natural eco-systems, and strategies for the scaling up of green-synthesized nanomaterials are discussed. With the extended work in enhancing nanomaterials synthesis performance, and discovering their biomedical, environmental, and agricultural applications, it is hoped that the execution of these methods on a large scale and their industrial applications in different fields will take place in the near future. - Assesses the impact of a large variety of silver-based nanostructures in the biomedical, environmental and agri-food sectors - Discusses the major synthesis methods used for effectively processing plant-based silver nanoparticles - Outlines the potential and major challenges for adopting green synthesis methods on a mass scale
