Gold nanostars outshine the competition
Novel nanoparticles being tested at the National Institute of Standards and Technology (NIST) have researchers seeing stars. In a recent paper, NIST scientists used surface-enhanced Raman spectroscopy (SERS) to demonstrate that gold nanostars exhibit optical qualities that make them superior for chemical and biological sensing and imaging. view more (2008-10-16)

MERCURY POLLUTION IN BOLIVIAN RIVERS
Mercury contamination in rivers of the Amazon Basin is increasingly a cause for concern. The region's soils, naturally containing abundant heavy metals, are one source of this mercury. Gold mining, which is an increasing activity in the Amazon region since gold fever took hold in the 1970s, is the additional major source. Many studies have been... view more... (1999-09-13)

NIST and partners identify tiny gold clusters as top-notch catalysts
For most of us, gold is only valuable if we possess it in large-sized pieces. However, the "bigger is better" rule isn't the case for those interested in exploiting gold's exceptional ability to catalyze a wide variety of chemical reactions, including the oxidation of poisonous carbon monoxide (CO) into harmless carbon dioxide at room... view more...

Gold nanoparticles prove to be hot stuff
Gold nanoparticles are highly efficient and sensitive "handles" for biological molecules being manipulated and tracked by lasers, but they also can heat up fast-by tens of degrees in just a few nanoseconds-which could either damage the molecules or help study them. view more (2006-09-01)
