Green synthesis of silver nanoparticles by candied carbohydrates such as glucose, starch and gelatin

In this work a fast, green and very simple synthesis method for the preparation of silver nanoparticles (AgNPs)with high concentration and high yield introduced. Silver nanoparticles (AgNPs) are currently among the most widelyused man-made nanomaterials, present in a huge range of consumer products. Synthesis of AgNPs was carried out at 100◦C temperature using glucose as reducing agent and starch as capping agent. The AgNPs were characterized usingtransmission electron spectroscopy, UV-Vis spectrophotometry, Dynamic light Scattering (DLS) and X-ray Diffraction(XRD). It was found that the synthesized Ag NPs have an average diameter of 50 nm. Further experiments showed thatsilver nanoparticles are water soluble, very stable and the nature of their production process is capable to scaling up.
