The Remarkable Uses of Gold in Technology and Industry

Gold has long been admired for its beauty and religious significance. However, its unique physical and chemical properties make it an indispensable material in various high-tech applications. This article examines the unique characteristics of this precious metal and its crucial role in various industries.

Gold in Electronics

Gold is an excellent conductor of electricity, which is why it is widely used in electronics. It is an essential component of many electronic devices such as smartphones, computers, and television sets. The metal’s ability to conduct electricity with a minimum of resistance ensures that electronic devices function with maximum efficiency. In addition, gold is corrosion-resistant, which protects electronic components from environmental hazards like moisture and oxygen.

The primary use of gold in electronics is bonding wires. Bonding wires connect electronic components to each other and the device’s substrate. These wires are made of ultra-thin gold. The gold’s ductility (ability to bend without breaking) is essential when bonding wires as they need to adhere to small, delicate components. When combined with other metals, gold is used to create electrical contacts and switches required for the functioning of electronic devices.

Gold in Medicine

Gold has been utilized in medicine for its positive side effects on the human body since ancient times. Today, the metal continues to have a critical role in modern medicine. The primary use of gold in medicine is treatment of rheumatoid arthritis, a chronic autoimmune disorder that affects the joints resulting in inflammation, swelling, and pain. Some arthritis patients have shown positive responses to the use of gold, and it is often used in a mixture with other medicines.

Of recent, it has also become common to use gold nanoparticles in medicine. The unique properties of these nanoparticles- their biocompatibility, ease of absorption and distribution by the human body, and surface area to volume ratio – have shown a strong potential for applications like drug delivery, cancer detection/prognosis, and imaging. Gold nanoparticles have also been researched for their antiviral capabilities; they may be used in measures to combat viruses by inhibiting viral entry into cells.

Gold in Aerospace

Gold’s use in aerospace is another notable application. The metal’s unique combination of excellent thermal and electrical conductivities with superior resistance to corrosion and radiation makes it most suitable for use in space. Gold is often used in antennae and on the surface of the spaceships for electromagnetic interference (EMI) shielding, which effectively protects the satellite’s delicate electronics from the harmful effects of solar radiation, particularly during solar flares.

Notably, some of the Voyager missions recently saw NASA deploy a gold-plated record aboard the spacecraft to communicate to potential life forms in the cosmos. The Golden Record contains multimedia samples of language, culture, images, and even sounds from Earth, all designed to offer an insight into life on our planet.

Gold in Jewelry Industry

The natural beauty of gold and the fact that it does not corrode or tarnish make it an ideal metal for jewelry. Due to its intrinsic value, gold signifies status and wealth, and is a must-have in any jewellery collection. The metal has been fashioned since ancient times to craft jewellery and other decorative pieces. Interestingly, gold’s value is a reflection of its supply (limited) and demand (high), making it an attractive choice for investment as well.

The metal is often combined with other materials to produce unique pieces of jewellery. The combination of gold and diamonds is especially well-regarded, with many considering it the forefront of luxury and class. It is also common to alloy gold compositionally, adding small percentages of other elements like copper and silver to affect the color or hardness of the gold, which allows jewellers to create gorgeous works of art.


Gold is a versatile and indispensable material that has played a significant role in human life for centuries. Its unique properties, including its conductivity, inertness, resistance to oxidation, and malleability, make it an essential component in various industries like medicine, aerospace, and electronics. There is no doubt that gold will continue to confer significant benefits to humanity as more applications are discovered and developed.
