Researchers at Case Western Reserve University have developed a little bomb that promises a big bang for cancer patients.
Preliminary tests show an anti-cancer drug loosely attached to gold nanoparticles starts accumulating deep inside tumors wit…
Scientists have created a diamond-like lattice composed of gold nanoparticles and viral particles, woven together and held in place by strands of DNA. The structure — a distinctive mix of hard, metallic nanoparticles and organic viral pieces known…
COLUMBIA, Mo. ¬¬¬ — Gold nanoparticles, tiny pieces of gold so small that they can’t be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer. Despite their positive uses, the process to m…
Detecting the presence of hazardous lead paint could become as simple as pressing a piece of paper against a wall and noting a color change. Scientists at the University of Illinois at Urbana-Champaign have developed a highly sensitive and selective biosensor that functions in much the same fashion as a strip of litmus paper.
Researchers have devised a way to use gold nanoparticles as tiny electrical wires to plug enzymes into electrodes. The gold “nanoplugs” help align the molecules for optimal binding and provide a conductive pathway for the flow of electrons. The research, described in the March 21, 2003, issue of Science, may yield more sensitive, inexpensive, noninvasive detectors for measuring biological molecules, including, potentially, agents of bioterrorism.
