title: Green synthesis of silver nanoparticles using Nelumbo nucifera seed extract and its antibacterial activity.
abstract: Silver nanoparticles (AgNPs) were synthesized using a Nelumbo nucifera dry seed extract, which is a simple, non-toxic, eco-friendly "green material". The synthesized nanoparticles were confirmed by the color changes and characterized by UV-visible spectroscopy. The AgNPs were stable at room temperature for 2 months. Scanning electron microscopy (SEM) revealed the formation of well-dispersed and spherical shapes. Transmission electron microscopy (TEM) of the synthesized AgNPs showed the formation of spherical nanoparticles, 5.03-16.62 nm in size. Fourier transform infrared spectroscopy (FTIR) indicated the involvement of amine, aromatic and alkynes groups in the synthetic process. X-ray diffraction (XRD) confirmed the crystalline nature of AgNPs. These AgNPs were highly toxic to found to Gram negative bacteria.
