Since silver is more reactive than gold, supplies of native silver were much more limited than those of gold For example, silver was more expensive than gold in Egypt until around the fifteenth century BC: [60] the Egyptians are thought to have separated gold from silver by heating the metals with salt, and then reducing the silver chloride produced to the metalNanotechnology is a rapidly growing field due to its unique functionality and a wide range of applications Nanomedicine explores the possibilities of applying the knowledge and tools of nanotechnology for the prevention, treatment, diagnosis and control of disease In this regard, silver nanoparticles with diameters ranging from 1 to 100 nm are consideredSilver nanoparticles: synthesis, characterisation and biomedical
