Abstract
A method of synthesizing silver nanoparticles includes using sesame (Sesamum indicum) oil cake extract as a reducing agent. The silver nanoparticles can range in size from about 6 nm to about 15 nm. The silver nanoparticles can have an average particle size of about 10 nm.
Claims12
A method of producing silver nanoparticles using Sesame indicum oil til cake after the Sesame indicum oil til cake has been washed to remove additives used in the Sesame indicum oil extraction process, comprising:
- providing a room-temperature dried Sesame indicum oil til cake, the Sesame indicum oil til cake being from the Makkah region of Saudi Arabia;
- grinding the sesame oil til cake to a fine powder;
- soaking the sesame oil til cake powder in distilled water for 24 hours;
- filtering the sesame oil til cake powder to produce sesame oil cake extract;
- adding distilled water to silver nitrate to obtain a silver nitrate solution;
- adding the silver nitrate solution to the sesame oil cake extract to provide a mixed solution;
- and
- maintaining the mixed solution for a period of time sufficient for formation of the silver nanoparticles, wherein the silver nanoparticles have a crystalline structure, are spherical in shape, and have an average particle size of 10.32 nm.
