【 摘 要 】

Crystallized Gold (Au), Silver (Ag), Strontium (Sr) tri-metallic nanometal alloy have been prepared and stabilised using plant extracts of coriander root (Coriandrum sativum) in an aqueous system. Aqueous solutions of Au+, Ag+, Sr+ ions are in 1: 1: 1 ratio of Au-Ag-Sr alloy was treated with a filtered solution of Coriandrum sativum root extract for the formation of Au-Ag-Sr trimetallic alloy nano particles (Au-Ag-Sr NP). Analysis of the feasibility of the biologically synthesized bio-functional core-shell nanometal alloy from plant root extract is particularly noteworthy. The colloidal suspensions obtained were in highly stable condition for 6-8 weeks. The prepared Au-Ag-Sr nanometallic alloy was then checked for the surface Plasmon resonance. The composition, morphology, size and structure of the nanoparticles were determined by Fourier transform infrared spectroscopy (FTIR) and field emission scanning electron microscopy (FESEM). Possible sensing applications of these tri- metallic alloy (Au Ag, Sr) nanoparticles are envisaged.
