About Gold Nanourchins

Gold Nanourchins are uniquely shaped gold nanostructures with uneven surfaces covered in nanoantenna-shaped spikes that cause a larger shift in the surface plasmon peak compared to uniform spherical gold nanoparticles. American Elements gold nanourchins have size-dependent absorption peaks ranging from 585nm to 680nm and are available with average particle sizes ranging from 50-100nm packaged in 0.1mM phosphate-buffered saline (PBS) solutions. Functionalized and conjugated forms are also available. Applications include biosensors, medical diagnostics, plasmon-enhanced or tip-enhanced spectroscopy, cancer therapies, and other biomedical and optical applications.

Gold

See more Gold products. Gold (atomic symbol: Au, atomic number: 79) is a Block D, Group 11, Period 6 element with an atomic weight of 196.966569. The number of electrons in each of Gold's shells is 2, 8, 18, 32, 18, 1 and its electron configuration is [Xe]4f142 5d10 6s1. Gold Bohr ModelThe gold atom has a radius of 144 pm and a Van der Waals radius of 217 pm. Gold was first discovered by Early Man prior to 6000 B.C. In its elemental form, gold has a metallic yellow appearance. Gold is a soft metal and is usually alloyed to give it more strength.Elemental Gold It is a good conductor of heat and electricity, and is unaffected by air and most reagents. It is one of the least reactive chemical elements. Gold is often found as a free element and with silver as a gold-silver alloy. Less commonly, it is found in minerals as gold compounds, usually with tellurium.
