UCF researcher's nanoparticles could someday lead to end of chemotherapy
Nanoparticles specially engineered by University of Central Florida Assistant Professor J. Manuel Perez and his colleagues could someday target and destroy tumors, sparing patients from toxic, whole-body chemotherapies. view more (2009-06-17)
Shape matters in the case of cobalt nanoparticles
Shape is turning out to be a particularly important feature of some commercially important nanoparticles-but in subtle ways. view more (2009-06-18)
Finding by Rice University chemists could aid development of new nanodevices
Rice University chemists have discovered that tiny building blocks known as gold nanorods spontaneously assemble themselves into ring-like superstructures. view more (2007-03-12)
Wrinkled membranes create novel drug-delivery system
A University of Illinois scientist studying how membranes wrinkle has discovered a novel system for on-demand drug delivery. view more (2006-02-15)
Microbes at work cleaning up the environment
It may sound counterintuitive to use a microbial protein to improve water quality. view more (2007-06-18)
Gold nanostar shape of the future
Rods, cones, cubes and spheres - move aside. Tiny gold stars, smaller than a billionth of a meter, may hold the promise for new approaches to medical diagnoses or testing for environmental contaminants. view more (2008-11-07)
Giving platinum catalysts a golden boost for fuel cells
Platinum might outweigh gold in the jewelry market, but as part of an ongoing effort to produce efficient and affordable fuel cells, scientists at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory are studying how gold atoms might enhance the value of the pricier metal. view more (2007-03-28)
Bacteria Precipitate Gold
Roman A. Amosov and a team of Russian scientists from the Central Institute for Geological Exploration of Non-ferrous and Noble Metals, Institute of Paleontology, Russian Academy of Sciences, and from the Institute of Microbiology, Russian Academy of Sciences, led by, have managed to simulate in the laboratory the process of precipitation of gold... view more...

Gold nanoparticle probes may allow earlier cancer detection
Using tiny gold particles embedded with dyes, researchers have shown that they can identify tumors under the skin of a living animal. These tools may allow doctors to detect and diagnose cancer earlier and less invasively. view more (2007-12-26)
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...

Researchers shed new light on catalyzed reactions
Rice University scientists on the hunt for a better way to clean up the stubborn pollutant TCE have created a method that lets them watch molecules break down on the surface of a catalyst as individual chemical bonds are formed and broken. view more (2008-11-20)
Controlling the Size of Nanoclusters: First Step in Making New Catalysts
Researchers from the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and Stony Brook University have developed a new instrument that allows them to control the size of nanoclusters - groups of 10 to 100 atoms - with atomic precision. view more (2008-07-10)
Nanocups brim with potential
Researchers at Rice University have created a metamaterial that could light the way toward high-powered optics, ultra-efficient solar cells and even cloaking devices. view more (2009-03-16)
Scientists meet to discuss health implications of nanoparticles
The possible health implications of nanoparticles will be discussed at a major academic conference, Nanotox 2004, taking place at the Daresbury Laboratories in Cheshire, UK, next week on Tuesday 13th and Wednesday 14th January. Nanotox 2004 is organised jointly by the Royal Microscopical Society and the Electron Microscopy and Analysis Group... view more... (2004-01-07)
Gold nanorods shed light on new approach to fighting cancer
Researchers have shown how tiny "nanorods" of gold can be triggered by a laser beam to blast holes in the membranes of tumor cells, setting in motion a complex biochemical mechanism that leads to a tumor cell's self-destruction. view more (2007-10-17)
Gold for the jubilee year
The Queen's Golden Jubilee year has been suitably marked by two British students, who were awarded gold medals at the International Biology Olympiad, held in Latvia. view more (2002-07-16)
New rotors could help develop nanoscale generators
In collaboration with the Chinese Academy of Sciences in Beijing, scientists have investigated the rotation of molecules on a fixed surface to understand how they may help in the development of future rotor-based machinery at nanoscale level. view more (2009-05-28)
When nano may not be nano
The same properties of nanoparticles that make them so appealing to manufacturers may also have negative effects on the environment and human health. view more (2009-09-14)
Novel approach estimates nanoparticles in environment
Without knowing how much of an industrial chemical is being produced, it is almost impossible for scientists to determine if it poses any threat to the environment or human health. view more (2009-05-21)
Clemson scientists shed light on molecules in living cells
Clemson University chemists have developed a method to dramatically improve the longevity of fluorescent nanoparticles that may someday help researchers track the motion of a single molecule as it travels through a living cell. view more (2007-08-21)
