| Abstract | In recent years, studies using the green chemistry approach for the synthesis of metallic nanoparticles (Nps) have been increasingly explored. Gold Nps (GNps) produced from natural compounds, such as hydroalcoholic extracts or essential oils from plants, can have greater stability, monodispersion, faster and more efficient synthesis, and can be an interesting alternative to conventional synthesis. In this work the seedless synthesis of gold nanorods (GNRs) using resveratrol (RSV), gallic acid (GA) and a fraction of the hydroalcoholic extract of Stryphnodendron obovatum was explored. The main objective was to characterize their stability and surface chemistry to demonstrate the natural products presence. Characterizations were made by Ultaviolet-Visible Absorption Spectrophotometry (UV–vis), Transmission Electron Microscopy (TEM), Zeta Potential, Fourier Transform Infrared Spectroscopy (FTIR) and X-Ray Photoelectron Spectroscopy (XPS). The results showed that the natural compounds used in the synthesis of GNRs favor the production of more stable particles, in addition to remaining anchored on its surface which reinforces, and allows us to suggest, several applications in the biomedical area of the GNRs thus produced. | pt_BR |
