RESUMO
The potential of ornamental plant Syngonium podophyllum leaf extract has been explored for the synthesis of silver nanoparticles, which was confirmed by appearance of absorption peak at 420 nm in ultraviolet-visible (UV-Vis) spectrum. Silver nanoparticles were predominantly spherical in shape and size observed under scanning electron microscopy (SEM) was in the range of 11 to 26 nm. A sharp signal recorded at 3 keV under energy-dispersive X-ray (EDX) spectrum indicated the presence of elemental silver nanoparticles. Zeta potential was measured as -26.77 mV, which indicated the presence of moderately stable silver nanoparticles in the solution. Under Fourier transform infrared (FTIR), two prominent bands were assigned, i.e., 3,454.89 cm-1 represents the O-H stretching vibration and 1,637.46 cm-1 represents the -NH stretching vibration of the amide group. It indicates that protein might be responsible for the synthesis.
