Gold is heavier than most other particles, so alternative methods typically use motion or water to separate the gold from lighter particles. Panning involves moving sediment that potentially contains gold in a curved pan with water and moving in such a way that any gold will settle at the bottom while the water and other particles will leave the pan.
Forming gold into nanoparticles allows researchers to use gold in areas that are too small for bulk gold to reach and brings with it new capabilities. For targeted drug delivery uses, it will be interesting to see whether gold nanoparticles show any benefit versus cheaper .
The opticalelectronics properties of gold nanoparticles are being explored widely for use in high technology applications such as sensory probes, electronic conductors, therapeutic agents, organic photovoltaics, drug delivery in biological and medical applications, and catalysis. Other applications of gold nanoparticles are listed below:

Other industries that rely on computers and microelectronics, such as aerospace, use large amounts of gold. According to the World Gold Council, NASA used more than kilograms (90 pounds) of gold in the construction of the Columbia space of it found its way into electrical contacts and circuit boards, but a large amount was used in thinfilm applications.
Gold nanoshells have also been synthesized via in situ gold nanoparticle formation using thermosensitive coreshell particles as the template (Suzuki and Kawaguchi 2005). The use of microgel as the core offers significantly reduced particle aggregation, as well as thickness control of the gold nanoshells using electroless gold plating.
Gold is the most useful mineral on the planet thanks to its variable properties. The luster has led to its use as jewelry. The metal can also be alloyed, pressed into thin sheets and wire drawn. The following are just some of the many uses of gold. Usage as Jewelry This metal has been utilized as jewelry since the time of the ancient Egyptians.
