Optimization of silver nanoparticles synthesis using Elaeis guineensis Jacq. residue extract and their antibacterial activity against Pseudomonas aeruginosa
Abstract This study explores the green synthesis of silver nanoparticles (Ag NPs) using oil palm (Elaeis guineensis) residue as a reducing agent. The synthesis was optimized by analyzing the effects of pH, silver nitrate (AgNO3) concentration, and extract-to-AgNO3 ratios using a Taguchi L9 design. T...

| description | Abstract This study explores the green synthesis of silver nanoparticles (Ag NPs) using oil palm (Elaeis guineensis) residue as a reducing agent. The synthesis was optimized by analyzing the effects of pH, silver nitrate (AgNO3) concentration, and extract-to-AgNO3 ratios using a Taguchi L9 design. The highest yield theorist (72%) was achieved under the conditions of pH 10, 100 mM AgNO3 concentration, and a 2:3 extract-to-AgNO3 ratio. The synthesized Ag-NPs were characterized through UV–Vis (400–450 nm), Fourier-transform infrared spectroscopy (FT-IR, 1370 cm-1, attributed to the nitro group), dynamic light scattering (DLS, 10.07 nm average particle size with a hydrodynamic diameter (Dh) of 235.82 nm in a neutral pH), zeta potential (− 18.33 mV), scanning electron microscopy (SEM), and X-ray diffraction (XRD). Antimicrobial testing against Pseudomonas aeruginosa revealed antibacterial activity, making these nanoparticles a promising alternative to traditional antibiotics. Graphical Abstract |
