Synthesis of Starch coated-AgNPs by arc-discharge method (ADM)

Silver nanoparticles (AgNPs) have several applications in nanoscience and nanomedicine such as antibacterial, antifungal, anti-inflammatory and anti-angiogenic properties. Most of their synthesis methods include chemical reduction and the use of stabilizing agents such as starch. In recent years, several green methods have been developed such as using carbohydrates as reducing agents. We report in this work a facile method for the synthesis of AgNPs under arc-discharge conditions. In this method, no reducing agents are used. In the present study, the AgNPs were synthesized by the chemical method and characterised using a combination of UV-Visible (UV-Vis) spectrophotometry, Fourier Transform Infra-Red (FTIR) spectroscopy, transmission electron microscopy (TEM) and X-ray diffraction (XRD). The AgNPs were made by arc discharge method to the formation of a characteristic yellowish-brown colour of AgNPs. Our method is particularly attractive owing to its use of water as green solution, along with short reaction times and without presence of chemical reducing agents.
