Over a billion cell phones were sold during the year of 2018. Gold is highly efficient in conducting electricity without corrosion, hence why it’s such a valuable commodity in the electronics industry. Every 1000 phones will yield just one troy ounce of gold. Most Smartphone’s contain a measly .001 troy ounce of gold. A little gold can go a long way in the electronics industry.
Other electronics that contain gold are; computers, GPS’s, personal digital assistants, and many more complicated electronics. Without gold, all electronics would be less reliable and lack in performance. Silver and copper are excellent conductors as well, but they are more likely to corrode than gold.
Considering the fact that cavities are the most common dental issue in the world, there’s a good chance that you or someone you know has gold in their mouth. The malleability of gold allows for it to be compressed into sheets of metal that are only a million of an inch in thickness. These thin sheets of gold are perfect for filling cavities and countless other implications. Since gold corrodes much slower than most metals, it’s the perfect material for fillings. Gold fillings, or inlays, will last for about 20 years.
Aside from the dental industry, gold has even more implications in the medical industry. A rare condition known as lagophthalmos is treated with the help of gold. Lagophthalmos is the inability to close the eyelids completely, hindering eye health and lubrication. Gold is surgically implanted into the upper eyelid to act as a weight in order to help the eyelids completely close.
Gold is also used to combat cancer and other diseases. Gold nano-particles in chemotherapy and radiotherapy are essential in fighting cancer and other bodily issues. Colloidal gold is a liquid substance comprised of gold molecules. Gold is the subject of substantial research due to its optical, electronic, and molecular-recognition properties. Colloidal gold can be used to detect and target cancerous tumors, optimize the distribution of drugs to diseased organs and cells, detect toxic gas and many more applications.
