Moscow State University scientists have used nanoparticles and changed the color of gold from sapphire to blue.
Scientists have turned the gold molecules to blue through a new technique for detecting cysteine (amino acids used in the composition of many drugs). Scientists have previously used an expensive way for detecting cysteine in metal formations by subjecting the gold molecules to “illumination” or “shine”.
The innovative method used by the Russian scientists can be briefed in transforming the color of gold molecules into blue, using the gold nanoparticles’ property of changing when combined in significant formations in the presence of ions of other metals and organic compounds, including cysteine. Chromatic changes that appear on gold can only be observed within 2 to 3 minutes through a special spectral device or by naked eye.
Cysteine is an amino acid that enters in the composition of Keratin which is found in nails, hair and feathers. It works on neutralizing the toxic substances in the body.
It is also of the antioxidants that protect the body from x-rays. Cysteine is used in medicines and supplements. A high incidence of cysteine indicates heart diseases, cardiovascular diseases and Alzheimer’s disease.
