Abstract :

Plants (such as tea) and fruits containnatural sources of antioxidants, which can act as reductants and are able reduce gold ions into gold nanoparticles (AuNPs). In this study, a simple and green synthesis of AuNPs has been achieved in tea leaves and fruits with gold ions. Natural antioxidants present in tea leaves and fruits were able to reduce Au3+ ions to make spheres of AuNPs.Different sizes of AuNPs were able to be synthesized with different teas and fruits since they contain a variety of antioxidants. Effect of pH on the formation of AuNPs was also investigated and the morphology of AuNPswas characterized by transmission electron microscopy. Our results indicated that the sizes of AuNPs were dependent on the types of fruits and the PHS of solutions.
