Method of inhibiting plant virus using gold nanoparticles

摘要

The method of inhibiting a plant virus using gold nanoparticles is a method of inducing plant resistance against viral disease caused by Barley Yellow Mosaic Virus (BYMV) particles by introducing a therapeutically effective amount of polydispersed gold nanoparticles to the plant through a mechanical abrasive, wherein the average effective diameter of the nanoparticles is between about 0.5 nm and 200 nm and wherein the gold nanoparticles are present at a concentration of about 1.0×10−5 g/ml to about 6×10−4 g/ml, and wherein the gold nanoparticles melt and dissolve the virus particles.

主权项

1. A method of inhibiting Barley Yellow Mosaic Virus (BYMV) or Barley Yellow Dwarf Virus (BYDV) using gold nanoparticles, comprising the steps of
a) introducing a solution consisting of a plurality of polydispersed gold nanoparticles suspended in water to a plant infected with BYMV or BYDV, wherein the gold nanoparticles have an average effective diameter of between 1.0 nm and 150 nm, the concentration of gold nanoparticles in the solution is about 0.00034 gm of gold nanoparticles in 1 ml of water, and b) directly applying the solution on leaf surfaces of the plant, and using a mechanical abrasive thereon; andwherein said gold nanoparticles surround and dissolve the BYMV or BYDV particles.
