2. Literature Review

In nanotechnology, nanomaterials are created at molecular level which exhibit qualities quite different from the bulk material. Bulk silver, when reduced to nano-level, shows remarkable changes in the properties making it more environments friendly and useful. Nano-silver can be defined as a group of micro-sized (nano) bits of silver that are either covering or suspended in a medium. Nanosilver exhibits unique physical and chemical properties compared to “conventional” silver (e.g., macro scale “bulk” silver). Nano silver of different shapes can be synthesized using various synthesis processes.
