Metal Dispersion

Gold nanoparticles dispersions are suspensions of gold nanoparticles in water or various organic solvents such as ethanol or mineral oil. According to the latest researches, the nanogold dispersions show similar antibacterial properties as the Nanosilver. Further, the nanogold is used as an additive in both cosmetic gels and creams by the cosmetic industry. It is advantageously applicable in the electric industry and sensor research due to its unique electrical conductivity and optical properties. The gold nanoparticles functionalized with different biomolecules are used in medical science as markers for different immune reactions.

Gold nanoparticles dispersion: Moreover, gold is a good conductor of heat and electricity. It is also soft and has been utilized to make ornamental objects and jewelry for thousands of years. Gold dispersion exhibit Special properties which make it suitable for manufacturing jewelry. The properties are very high luster; desirable yellow color; tarnish resistance; ability to be drawn into wires, hammered into sheets, or cast into shapes. These are all properties of an alluring metal that are easily worked into beautiful objects.

Because gold is highly valued and in very limited supply, it has long been utilized as a medium of exchange or money. Early transactions were done usually using pieces of gold or pieces of silver. The rarity, usefulness, and desirability of gold form it a substance of long-term value. Gold nanoparticles dispersion works well for this purpose due to it has a high value, is durable, portable, and easily divisible.

A small amount of gold dispersion is utilized in almost every sophisticated electronic device. This involves cell phones, calculators, global positioning system (GPS) units, personal digital assistants, and other small electronic devices. Most large electronic appliances for instance television sets also contain gold. Electronic components manufacturer with gold is highly reliable. Gold nanoparticles dispersion is employed in connectors, switch and relay contacts, connecting wires, soldered joints, and connection strips.

Gold nanoparticles dispersion is applied in dentistry due to its superior performance and aesthetic appeal. Gold nanoparticles dispersion is utilized for fillings, crowns, bridges, and orthodontic appliances. Gold dispersion is used in dentistry owing to it is chemically inert, non-allergenic, and easy for the dentist to work. Gold is applied as a drug to treat a small number of medical conditions. In diagnosis, radioactive gold is employed. Many surgical instruments, electronic equipment, and life-support devices are fabricated using small amounts of gold.
