Silver Nanoparticle Control Of Resistance To Plant Disease

- Oct 10, 2017 -

Although nanoparticles sound like recent discoveries, Silver Nanoparticle this tiny structure has actually been used for hundreds of of years. The famous Lecorgus Cup (Lycurguscup), produced by the Roman artisans of the year Fourth century, is equipped with two-colored glass, sprinkled with gold and silver nanoparticles on the surface of the cup, and when the light shines from the front of the cup, Silver Nanoparticle it presents a green appearance, when the light shines from behind.

Since the age of ancient craftsmen, Silver Nanoparticle researchers have been deeply aware of nanoparticles. The potential use of nanotubes as biosensors and gas sensors has made people particularly interested in it. Nanoparticles can be prepared using physical or chemical methods, which are better than chemical methods because physical methods do not generally use organic contaminants. But in a physical way, it is difficult to produce a uniform size and a sufficient number of nanotubes.

Cube shape is not the lowest energy structure of iron nanoparticles, and we cannot rely on equilibrium thermodynamics to consider the self assembly of these nanotubes. Silver Nanoparticle Instead, Olst scientists, under the guidance of Professor Mukhles Sowwan, developed a new method called magnetically controlled sputtering inert gas condensation technology to produce iron nanotubes. First, Silver Nanoparticle the argon is heated to become ionized plasma, and a magnet is placed behind the target of the desired material to control the shape of the plasma and to ensure that the argon ion targets the target, hence the name "Magnetron". The final iron atom is sputtered off the target, colliding with the argon atom and forming nanoparticles. By controlling the magnetic field, Silver Nanoparticle the plasma is precisely controlled to achieve the aim of producing even nanotubes.

Silver nanoparticles diameter in 5~100 Nano, about 1 per thousand of human hair. Once nanoparticles are sprayed on plants, they protect plants from fungal invasions. Nanoparticles also show a variety of ways to inhibit the growth of fungi, minimizing the chance of the pathogen producing resistance. Silver Nanoparticle As a result, they can be used for more effective control of resistant plant pathogens.

Silver nanoparticles are being studied in various industries, Silver Nanoparticle including pharmaceuticals, diagnostics, cosmetics and food processing. They have been successfully used in wound dressings, food packaging and consumer products such as textiles and footwear to prevent microbes from producing odors.
