- Scientists design simple dipstick test for cocaine, other drugs
11-13-2006 · EurekAlert!
Researchers at the University of Illinois at Urbana-Champaign have developed a simple "dipstick" test for detecting cocaine and other drugs in saliva, urine or blood serum. The test is based upon DNA-gold nanoparticle technology, and can be packaged in user-friendly kits similar to those used for home pregnancy tests.

- Adenine 'tails' make tailored anchors for DNA
12-22-2006 · EurekAlert!
Researchers from NIST, the Naval Research Laboratory and the University of Maryland have demonstrated a deceptively simple technique for chemically bonding single strands of DNA to gold. The technique offers a convenient way to control the density of the DNA strands on the substrate, which could be important for optimizing DNA sensor arrays.

- Gold nanoparticles help detect a toxic metal -- mercury
04-27-2007 · EurekAlert!
With gold nanoparticles, DNA and smart chemistry as their tools, scientists at Northwestern University have developed a simple "litmus test" for mercury that eventually could be used for on-the-spot environmental monitoring of bodies of water, such as rivers, streams, lakes and oceans, to evaluate their safety as food and drinking water sources. An article detailing the technology's success will be published online April 27 by Angewandte Chemie, the prestigious European journal of applied chemistry.

- DNA is blueprint, contractor and construction worker for new structures
01-30-2008 · EurekAlert!
DNA is the blueprint of all life, giving instruction and function to organisms ranging from simple one-celled bacteria to complex human beings. Now Northwestern University researchers have used DNA as the blueprint, contractor and construction worker to build a 3-D structure out of gold, a lifeless material. Using just one kind of nanoparticle the researchers built two very different crystalline structures by changing one thing -- the strands of synthesized DNA attached to the tiny gold spheres.

- DNA Highly Promising Predictor For Successful Treatment Of Alcoholics
10-05-2006 · ScienceDaily
According to Dutch researcher Wendy Ooteman, the biological and genetic characteristics of alcoholics can predict which drugs will best suppress the desire to drink. Naltrexone and acamprosate are drugs that are supposed to suppress the desire for a drink. The researcher investigated which patient characteristics were responsible for predicting the drug that would work best.
