Currently, nano silver particles have been interested in the study are numerous. Because such particles have several features of interest. Can be applied such as in medicine. Can be used for sterilization and production equipment for the surgery. Industrial use of nanoparticles as catalysts. It also can lead to nano-sized silver particles used in the electronics industry. In agriculture, too. And today Produce has been produced for commercial purposes such as washing sheets, wound dressings, cosmetics, food industry and others [1] of the anti-infectious properties. Nano-sized silver particles to kill bacteria. The crystalline nano-sized silver particles have more surface area exposed to the bacteria has an opportunity as well. This resulted in the killing of bacteria increased. Nano-sized silver particles interact with the protein. In general, bacteria are a major component of protein. So when [2] The nano-sized silver particles exposed to microorganisms. To the collection and insertion into the cell wall. On the other hand, among -SH (Sulfphydryl) well, which is among the components of the enzyme. This process affects bone metabolism and cause methadone inhibits the growth of cells. Lead to the destruction of the respiratory system. System to transport electrons in the metallic ribbon metabolism and transport of substrates in the membrane [3] In addition, the particle size nanoparticles can also be used to inhibit the proliferation and growth of microorganisms that cause. infection, odor, itching and ulceration as well [4] However, the effect of nano-sized silver particles on plants is also being studied quite limited. So this project is to study the effects nanoparticles on plants. Also interested to study the synthesis conservative Indian nano reduce the toxicity of chemicals with a synthetic particle silver nanoparticles can be done in many ways such as reducing agents chemically (chemical reduction) discharge Sparks (spark discharge. ) and irradiated solution (solution irradiation) and others how to use the other two methods is synthesized by chemical means [1] and synthesized by radiation [2, 5, 6] principles. in general, the synthesis of metal nano-particles is. Reducing the oxidation of the metal into a neutral atom of the metal (zerovalent) metal atoms are then captured into nanoparticles. The compounds are stable to maintain the size of the nanoparticles. This is usually the type of polymer. The polymer to prevent the capture of particles Winona. But because the chemical reducing agent by the most highly toxic. It is not commonly used in the preparation of nanoparticles used in biology. But the use of synthesis methods, irradiation does not require the use of chemicals that are toxic. It can be applied in the preparation of nanoparticles using biological. The silver nanoparticles by radiation is also a convenient way. And can control the size of the metal nano-particles [2] The solution used for the synthesis of nanoparticles comprising a compound of polyvinyl alcohol (PVA) to prevent the capture of isopropanol nanoparticles to bind with oxidizing substances. Preparation of nano-sized silver particles with radiation. The solution is irradiated to induce nanoparticles. Radiation causes the solution to radicals and compounds. According to the following equation [2, 5, 6].
