Gold, in addition to being a precious stone, is an element with great light emission properties and can have great value in medicine, genetics and chemistry. Lighting a chemical element excites and emits fluorescent light. They are the duration of the light emitted by the separation of gold and the necessary conditions for it. The light emitted is a million times longer than observed so far, but for this the distance between atoms must be 3.5 angstroms and not be interactive with other components.
This second property in medicine translates into the analysis of light emitted by gold atoms to detect diseases.
