Nanotechnology is defined as the understanding, manipulating and controlling things at the nanoscale, where the unique properties of materials arises that enable novel applications. Gold is considered to be noble among all metals due to its resistance to surface oxidation because of this, it is known as the king of the metals. Contrary to the nobility of bulk gold, exciting properties can be attributed to gold at the nanoscale. Gold nanoparticles (AuNps) can be used for clinical developments in cell labeling, providing contrast in biological imaging, drug design and time bound delivery at the...
