In the field of nanotechnology, the synthesis of metallic nanoparticles (NPs)
is a demanding task for both modern phytopharmaceutical research as well as
academics. These metallic nanostructures, NPs, made of metals such as gold and silver
NPs can be used as quantum dots for the applications in Biomedical Science and
Technology. Nanomedicine is a newly developed branch that is a boon for modern
medicine. Nanotechnology in medicines will increase the production of the intended
results and safety of the medicine. Nanoparticles are known for their stability,
solubility, absorption and reduced toxicity. Metallic nanoparticles have been used for
treatment in some life-threatening diseases such as cancer. This chapter introduces gold
and silver nanoparticles, nanoshells and nanocages and their physico-chemical
properties, and illustrates some of the recent advances in the field of diagnostic
imaging and cancer therapy. Nanotechnology had a great influence on medical science
and made a remarkable progress in the field of diagnostics.
