Nanotechnology thermal properties 4-7. But now days some

Nanotechnology and Nanoscience is the most prominent area in the scientific research, in the past few years green synthesis of the metal nanoparticles becoming more popular in the field of nanoscience and nanotechnology because it is less expensive and ecofriendly technique 1-3. The various methods for the preparation of the gold nanoparticles has been proposed such as fruit extract, plant extract, seed extract, leaf extract, multivitamins and microorganism has been used as reducing and capping agents. The most important application of the gold nanoparticles is in the field of biomedical, nanomedicine, Drug delivery and detection of the tumor and cancer because their unique optical and thermal properties 4-7. But now days some other toxic chemical have been used as reducing and stabilizing agents the nanoparticles which are produced through these chemicals are highly toxic and not safe for human applications, these regents are not good to living organism and also not safe for the environment, proper handling and precautions are required when using these reducing agents, some microorganisms are also reported for the synthesis of nanoparticles.8. Various plants, fruits and seed extract have been used for the green synthesis of gold nanoparticles Such as, Leaf extracts of neem9, Aloe-vera 10, Wheat 11, tamarind 12 and Coleus aromaticus was used 13, Garcinia mangostana was used 10, Barbated skullcup herb extract was used 11, Magnolia kobus and Diopyros kaki leaf extracts were used 12, Rosa hybrid petal extract was used 13, Nyctanthes arbortristis ethanolic flower extract was used 14, Cassia fistula leaf was used 15, Lippia citriodora (Lemon verbena) leaves extract was used 16 for gold nanoparticles synthesis. Stability of green gold nanoparticles through heating and other techniques was analyzed. Gold nanoparticles shows antibacterial activities 17,18.Green synthesis Using plants, fruits and seed extract of nanoparticles could be benefited over the chemically and biological methods for the production of green gold nanoparticles, green synthesis can also be applied for the large scale production of the green gold nanoparticles. In this present research work, we synthesized and characterized green gold nanoparticles using maze extract.
Materials and Methods-
The green synthesis of the gold nanoparticles was carried out from maze extract; Yellow corn granules were purchased from local market Allahabad and Gold(III) chloride was purchased from Sigma-Aldrich ,USA: 99.99%.Mature Corn granules were dried in direct sunlight then washed thoroughly with double distilled water. The corn granules were grind into fine powder then 100gm fine powder was mixed with 500ML deionized water and boiled for 50 minutes and centrifuged at 5000 rpm and filtered through whatman no. 1 filter paper. The maze extract solution was used after 2 hours of preparation. The filtrate solution was used as reducing and stabilizing agents for the further experimental process.
Synthesis of Gold nanoparticles-
For the production of the green gold nanoparticles 10ML of seed extract solution was added to the 100 ML of Gold Chloride solution (0.001M) with continuous magnetic stirring without heating. The solution was kept for 90 minutes at room temperature. The color changes yellow to ruby red ensure the formation of green gold nanoparticles. The properties of the gold nanoparticles like physical, optical, magnetic depends upon the preparation process and reducing agents, the ruby red solution was further used for characterization of the green gold nanoparticles
