Nanotechnology is still on its early stage of development and yet, it already constitutes vast range of applications but only few methods are known to synthesize these nanomaterials. In this study, another biosynthesis of silver nanoparticles (AgNPs) was exemplified and is more efficient and economical alternative for large-scale resolves. Starch from Nypa fruticans (Nipa) seeds had ministered the synthesis of AgNPs as both reducing and capping agent. Nipa starch first undergone series of physical property tests and compared it to commercial corn starch. Thereafter, the synthesis of AgNPs through reduction method was done in a thirty-minute reaction period and the resulting AgNPs were further characterize through UV-Vis Spectroscopy in which resulting peak confirms the presence of AgNPs and Scanning Electron Microscopy (SEM) in which the surface morphology of the sample was determined. The AgNPs was identified to have a rod-like shape and has a diameter of 30um at x2000 and x25000 magnification. The present study shows a new way of synthesizing AgNPs which can further be applied to various applications and more importantly a potential breakthrough for the field of nanotechnology.
