Multi-laboratory study sizes up nanoparticle sizing
As a result of a major inter-laboratory study, the standards body ASTM International has been able to update its guidelines for a commonly used technique for measuring the size of nanoparticles in solutions. view more (2009-08-12)
Gold Nanorods May Make Safer Cancer Treatment
Researchers at the Georgia Institute of Technology and the University of California, San Francisco, have found an even more effective and safer way to detect and kill cancer cells. view more (2006-03-14)
Tightly packed molecules lend unexpected strength to nanothin sheet of material
Scientists at the University of Chicago and Argonne National Laboratory have discovered the surprising strength of a sheet of nanoparticles that measures just 50 atoms in thickness. view more (2007-07-23)
Strengthening Fluids With Nanoparticles
Researchers at Rensselaer Polytechnic Institute have demonstrated that liquids embedded with nanoparticles show enhanced performance and stability when exposed to electric fields. The finding could lead to new types of miniature camera lenses, cell phone displays, and other microscale fluidic devices. view more (2008-02-20)
Researchers make nanosheets that mimic protein formation
University of Michigan researchers have discovered a way to make nanocrystals in a fluid assemble into free-floating sheets the same way some protein structures form in living organisms. view more (2006-10-13)
New disease-fighting nanoparticles look like miniature pastries
Ultra-miniature bialy-shaped particles - called nanobialys because they resemble tiny versions of the flat, onion-topped rolls popular in New York City - could soon be carrying medicinal compounds through patients' bloodstreams to tumors or atherosclerotic plaques. view more (2008-07-30)
Researchers demonstrate use of gold nanoparticles for cancer detection
Binding gold nanoparticles to a specific antibody for cancer cells could make cancer detection much easier, say medical researchers from the University of California, San Francisco and Georgia Institute of Technology. view more (2005-06-03)
Novel experiments on cement yield concrete results
Using a brace of the most modern tools of materials research, a team from the National Institute of Standards and Technology (NIST) and Northwestern University has shed new light on one of mankind's older construction materials—cement. view more (2007-04-02)
Shining sweetness â€" fluorescent sugars shed new light on future TB therapies
The discovery that fluorescent sugar molecules mark important enzymes of the tuberculosis bacillus will facilitate investigation of the potential importance of the enzymes for future tuberculosis (TB) therapies. This insight is a gratifying "by-product" of research at the Institute of Organic Chemistry at the Graz University of... view more... (2003-05-19)
Magnet Lab researchers make observing cell functions easier
Now that the genome (DNA) of humans and many other organisms have been sequenced, biologists are turning their attention to discovering how the many thousands of structural and control genes -- the "worker bees" of living cells that can turn genes on and off -- function. view more (2008-05-09)
Fishing in the dark
Nanotechnology is a relatively new scientific field that holds immense promise for the future. A nanometer is one millionth of a millimeter, and nanoparticles form the basis of completely new materials for pharmaceutical, cosmetic, electronic and optical applications. The size and structure of the particles are decisive in regulating the optical,... view more... (1999-09-03)
Scientists advance safety of nanotechnology
Scientists have identified for the first time a mechanism by which nanoparticles cause lung damage and have demonstrated that it can be combated by blocking the process involved, taking a step toward addressing the growing concerns over the safety of nanotechnology. view more (2009-06-11)
Berkeley Researchers Find New Route to Nano Self-Assembly
If the promise of nanotechnology is to be fulfilled, nanoparticles will have to be able to make something of themselves. An important advance towards this goal has been achieved by researchers with the U.S. Department of Energy's Lawrence Berkeley National Laboratory (Berkeley Lab) who have found a simple and yet powerfully robust way to induce... view more...

Formation of cellulose fibers tracked for the first time
Cellulose-a fibrous molecule found in all plants-is the most abundant biological material on Earth. view more (2006-04-21)
New nanoparticles could revolutionize therapeutic drug discovery
A revolutionary new protein stabilisation technique has been developed by scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) which could lead to 30 per cent more proteins being available as potential targets for drug development - opening up exciting possibilities in drug discovery. view more (2009-06-26)
U-M researchers use nanoparticles to target brain cancer
Tiny particles one-billionth of a meter in size can be loaded with high concentrations of drugs designed to kill brain cancer. view more (2006-11-15)
Clemson bioengineer uses nanoparticles to target drugs
Clemson bioengineer Frank Alexis is designing new ways to target drugs and reduce the chances for side effects. view more (2009-10-09)
Seeing previously invisible molecules for the first time
A team of Harvard chemists led by X. Sunney Xie has developed a new microscopic technique for seeing, in color, molecules with undetectable fluorescence. view more (2009-10-26)
Live recordings of cell communication
A new advanced method for nano-scale imaging of vesicle-fusion - vesicles are biological nano-sized containers - could add to our understanding of diseases of the nervous system and viral infections. view more (2009-08-06)
NIST researchers 'all aglow' over new test of toxin strength
A new National Institute of Standards and Technology (NIST) assay using a "glow or no glow" technique may soon help the U.S. Department of Homeland Security (DHS) defend the nation against a spectrum of biological weapons that could be used in a terrorist attack. view more (2009-06-18)
