The Properties of material is determined by the space available for their electrons to undergo their characteristic motion. This space ranges from 1-100 nm for the different materials around us. If the material size changes below its characteristic size, its property changes and becomes new material and its property become sensitive to further changes in size or shape. The important new properties of metallic Silver and Gold having nanometer sizes will be discussed. Their new optical and photothermal properties will be detailed and used in detecting, treating and following the dynamic properties of alive cancer cells and as they die.
