Company: Jayant Agro: Silver Nano Particle production using Castor

Currently, nanoparticles (NPs) are used in several scientific applications, but among these silver nanoparticles (Ag-NPs) are predominant. This is because of several characteristic features of this type of metal NP.
Antimicrobials and nanocomposite fabrication are some of the highly useful applications, among others, of applications that were attributed to Ag-NP.

In the fabrication of NPs, it is very important to control particle size, shape, and morphology.
Laser ablation in liquid media is a simple and clean method for synthesis of NPs.
In this technique, there is no need to use any chemical reagents (such as NaBH4) in the fabrication process or any purification techniques to characterize the produced NPs.

Ag-NPs have been successfully prepared in castor oil by laser ablation from a silver plate. The results obtained showed that the produced Ag-NPs were well dispersed and also stable
for quite a long period of time. This ability of castor oil to prevent agglomeration of Ag-NPs is due to the presence of long-chain hydrophobic moieties.
