Abstract

The article highlights the synthesis, properties and recent advances in therapeutic possibilities of metallic nanoparticles. Nanometallic structures that behave as drug-carrying agents, gene regulators, imaging agents and photoresponsive assemblies have been discussed in the context of cells and many debilitating diseases. These structures not only act as alternatives to molecule-based systems, but also possess new physical and chemical properties, which confer substantive advantages in medicinal field.
