Effect of gold nanoparticles on germination status of cereals

Nanotechnology is a branch of biology which deals with study of nano-materials, nanoparticles and its applications. Nowadays, nanotechnology occupies a large area due to its importance in the entire field. Pharmacological industries and textile industries were solely dependent on the use of nanoparticles. Biological method is a good alternative source for the production of nanoparticles as compare to physical method and chemical methods. Microorganisms provide good alternative for the same due to its large availability and cheapest investment. Fungi have capacity to multiply rapidly, so it can be used for the production of nanoparticles. In the present investigation different species of Penicillium was used for the production of gold nanoparticles. The color of cell free filtrate turned into different shades of purple color which indicates the synthesis of gold nanoparticles. Effect of these synthesized gold nanoparticles was tested against Wheat, Jowar and Bajra; which shows significant results in germination status of these cereals.
