Abstract [en]

Silver nanoparticles (AgNPs) were biosynthesised by reducing silver nitrate (AgNO3) using Ambrosia maritima aqueous leaves extract. The biosynthesised AgNPs were characterised by transmission electron microscope, Fourier transform infrared spectroscopy and zeta potential analyser. The nanoparticles were generally found to be spherical in shape with average size of 30 nm and were stable at zeta potential of -26.29 mV. The data collected by cyclic voltammetry, ultraviolet-visible (UV-Vis) spectrophotometer and spectrofluorophotometer proved the characteristic electrochemical and optical properties of the biosynthesised AgNPs. The metallic nanoparticles showed an anodic peak at 0.4 mV, a surface plasmon resonance peak at 437 nm and a fluorescence emission peak at the wavelength of 467 nm. In conclusion, AgNPs biosynthesised using A. maritima proved to be compatible and feasible to be studied further in in vitro and in vivo systems. Overall, the biosynthesised AgNPs can be used as a tool applied in a broad range of industrial and medical applications.
