| Abstract |
| Chlorogenic acid (CGA), a major class of phenolic compounds abundant in green coffee beans, are well known for their antioxidant, antimicrobial, anticancer, and therapeutic properties. They have attracted increasing attention as sustainable reducing and stabilizing agents in nanotechnology. This study focuses on the extraction of CGA from green coffee beans and uses its enriched fraction in the biosynthesis of metal nanoparticles. The synthesized nanoparticles were systematically characterized using UV-Vis spectroscopy, transmission electron microscopy (TEM), X-ray diffraction (XRD), and Fourier-transform infrared spectroscopy (FTIR), confirming their successful formation, stability, and structural features. Furthermore, the biological activities of CGA-conjugated nanoparticles were assessed, with particular emphasis on their antioxidant and antimicrobial properties. The results demonstrated enhanced bioactivity compared to free CGAs, highlighting the synergistic effects of combining natural phenolic compounds with nanometals. This study underscores the potential of integrating natural products with green nanotechnology, paving the way for sustainable applications in medicine and environmental science. |
