By adding this extract to silver nitrate solutions, the researcher observed a distinct color change to wine-red after incubation, signaling the formation of nanoparticles via surface plasmon resonance. Comprehensive characterization using UV-Vis spectroscopy, Dynamic Light Scattering (DLS), and Transmission Electron Microscopy (TEM) confirmed the production of spherical, nano-crystalline silver particles with desired size and shape. Structural and elemental validation was further provided by X-ray Diffraction (XRD), which identified standard facets of silver, and Energy Dispersive X-ray Spectroscopy (EDX), which verified the elemental composition. Finally, antibacterial testing using the disc diffusion method demonstrated that these biologically synthesized nanoparticles effectively inhibit the growth of both Gram-positive and Gram-negative bacteria, suggesting significant potential for future applications in medicine, textiles, and advanced electronics.", "item_img_path" : "https://covers3.booksamillion.com/covers/bam/6/20/971/661/620971661X_b.jpg", "price_data" : { "retail_price" : "58.00", "online_price" : "58.00", "our_price" : "58.00", "club_price" : "58.00", "savings_pct" : "0", "savings_amt" : "0.00", "club_savings_pct" : "0", "club_savings_amt" : "0.00", "discount_pct" : "10", "store_price" : "" } }
