Since gold nanoshell-composite hydrogels were reported to release chemicals and proteins in response to near-infrared irradiation, gold nanoshells could be used as efficient drug carriers [59]. Therefore, gold nanoshells could be powerful therapeutic drug vehicles with near-infrared lightassisted dual functions of heat generation and controlled drug release [60] .

In gold recovery processes, it is used as a neutralizer of excess nitric acid in aqua regia solutions. To make aqua regia solution you will need Hydrochloric Acid and Nitric Acid. These are sold separately from this kit. This kit is a convenient

Toxic chemicals are used in the Flotation Process to separate the copper and molybdenum out of the milled powder. This Flotation process is the major extraction method at Duval/Sierrita mine because of the poor quality of the copper at this site. Some chemicals produce bubbles that that the copper adheres to and the "bad stuff" falls to the bottom.
