This is because of the wider application of nanotechnology material in various kinds of field. At present, metal nanoparticles have been intensively investigated because of their extensive usage. In recent year, the use of metal nanoparticles such as iron, silver and nickel have been paid considerable attention because of the wider application of nanoparticles in different fields (Xu et al.,2007). Previously, nanoparticles have been produced mainly by chemical solution processes. This process used some chemicals that has possibility to act as a reducing agent, capping agents, and organic solvents that can produce nanoparticles.

In this project, HEC was used to synthesize silver metal into metallic nanoparticles and characterize the morphology formed by using HR-TEM, SEM and UV-Vis.

description The development in the field of nanotechnology and nanoscience has attracted much attention over the past decade. This is because of the wider application of nanotechnology material in various kinds of field. At present, metal nanoparticles have been intensively investigated because of their extensive usage. In recent year, the use of metal nanoparticles such as iron, silver and nickel have been paid considerable attention because of the wider application of nanoparticles in different fields (Xu et al.,2007).
