Abstract

Background: Biological synthesis of nanoparticles for various biomedical applications has gained interest in recent years due to its biocompatibility. Aim: The aim of the present study is to synthesize gold nanomaterials using plant Catharanthus roseus as an eco friendly approach. Results: The treatment of aqueous solution of chloroauric acid with root extract of C. roseus led to the rapid formation of Gold Nanoparticles (AuNPs). The color change and the Surface Plasma Resonance (SPR) confirmed the formation of AuNPs. Atomic Force Microscopy (AFM) was used to study the shape of the nanoparticles and X-Ray Diffraction (XRD) used to study the phase purity of the nanoparticles. The UV-vis spectra of the nanoparticles showed absorbance maxima peak at 538 nm. Transmission Electron Microscopy (TEM) showed spherical and triangle shaped nanoparticles with average size ranging from 30 – 60 nm as a result of plant extract concentration variation. Conclusion: The nanoparticles were found discrete with spherical and triangle shape dominant.
