Biogenic Synthesis and Characterization of Silver Nanoparticles Using Hoya Carnosa Flower Extract

Silver nanoparticles (AgNPs) are important metallic nanomaterials thanks to their superior antibacterial properties and wide application areas; however, conventional synthesis methods are quite limiting in terms of environmental and economic aspects. This situation causes green synthesis methods to be investigated more and more. Hoya carnosa plant have the potential to be an alternative biogenic synthesis agent to traditional methods thanks to their rich phytochemical content. In this study, biogenic AgNPs were synthesized for the first time using Hoya carnosa flower extract. The reaction was completed in a short time, such as 15 min under room conditions. AgNPs were comprehensively characterized by UV-Vis, FTIR, XRD, SEM, TEM and EDX analyses. According to the obtained results, the average size of AgNPs was calculated as 16 nm by the Debye Scherrer equation and 21 nm by TEM analysis. This study demonstrates that the use of Hoya carnosa flower extract can be a successful alternative to traditional methods by contributing to the synthesis of AgNPs in an environmentally friendly and rapid manner.
