To develop a simple rapid procedure for bioreduction of gold nanoparticles (AgNPs) using aqueous plant extracts of Catharanthus roseus (C. roseus) Characterization were determined by using UV-Vis spectrophotometry, Field Emission scanning electron microscopy (FESEM), energy dispersive X-ray and X-ray diffraction. FTIR, DLS, MCF-7 Brest cancer. The result reveals FESEM showed the formation of gold nanoparticles with an average size of 25 nm X-ray diffraction analysis showed that the particles were crystalline in nature with face-centered cubic geometry. Dynamic light scattering analysis reveals the average particle size 25nm and FTIR Analysis reveal the functional group and biomolecules are present the gold nanoparticles. C. roseus demonstrates strong potential for the synthesis of Gold nanoparticles by rapid reduction of gold ions (Au+ to Au0 ). This study provides evidence for developing large scale commercial production of value-added products for biomedical/nanotechnology-based industries.
