Abstract
Silver nano-disks have been synthesized by using starch as reducing- and stabilizing agent for the first time. UV-visible spectroscopy, transmission electron microscopy (TEM) and iodometric techniques were used to monitor the quantitative growth, and morphology of Ag-nanoparticles. The polyhedral nano-disks with an average diameter of 500 nm contain a large number of truncated triangular nanoplates, spherical, quantum dots, and irregularly shaped nanosilver were formed with starch. The silver nanodisks with an average diameter 500 nm contain a large number of truncated triangular and spherical nanoplates and quantum dots, and irregularly shaped nanosilver were formed with starch. The cetyltrimethylammonium bromide (CTAB) markedly enhanced the reaction path and changed the morphology (size, shape and distribution). This environmental friendly method of biological silver nanoparticle production provides the use of starch as a capping agent. (C) 2014 Elsevier B.V. All rights reserved.
