New 'adjuvant' could hold future of vaccine development
Scientists at Oregon State University have developed a new "adjuvant" that could allow the creation of important new vaccines, possibly become a universal vaccine carrier and help medical experts tackle many diseases more effectively. view more (2009-09-15)
"Nanominerals" Influence Earth Systems from Ocean to Atmosphere to Biosphere
The ubiquity of tiny particles of minerals--mineral nanoparticles--in oceans and rivers, atmosphere and soils, and in living cells are providing scientists with new ways of understanding Earth's workings. Our planet's physical, chemical, and biological processes are influenced or driven by the properties of these minerals. view more (2008-03-24)
Nanotech safety needs specific government risk research strategy and funding
"Prioritizing nanotechnology risk research isn't rocket science," said Project on Emerging Nanotechnologies chief scientist Andrew Maynard. Dr. Maynard's remark is in his testimony today before the federal government's first public meeting focused exclusively on research needs and priorities for the environmental, health and safety risks... view more...

Twinkling nanostars cast new light into biomedical imaging
Purdue University researchers have created magnetically responsive gold nanostars that may offer a new approach to biomedical imaging. view more (2009-07-22)
Nanoscale dimensioning is fast, cheap with new NIST optical technique
A novel technique under development at the National Institute of Standards and Technology (NIST) uses a relatively inexpensive optical microscope to quickly and cheaply analyze nanoscale dimensions with nanoscale measurement sensitivity. view more (2008-10-30)
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)
Direct photon properties reveal secrets of extreme nuclear states
When atomic nuclei are smashed together at great speed, resulting temperatures exceed one trillion degrees, 200 million times hotter than the surface of the sun. view more (2006-04-26)
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)
Laser Surgery Probe Targets Individual Cancer Cells
Mechanical engineering Assistant Professor Adela Ben-Yakar at The University of Texas at Austin has developed a laser "microscalpel" that destroys a single cell while leaving nearby cells intact, which could improve the precision of surgeries for cancer, epilepsy and other diseases. view more (2008-06-25)
Nanoparticles create biocompatible capsules
An innovative strategy of mixing lipids and nanoparticles to produce new drug and agricultural materials and delivery vehicles has been developed by researchers at the University of Illinois at Urbana-Champaign. view more (2006-03-07)
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)
New protein synthesis not essential to memory formation
New research from the University of Illinois challenges the premise that the brain must build new proteins in response to an experience for that experience to be recorded in long-term memory. view more (2007-07-27)
Novel 3-D cell culture model shows selective tumor uptake of nanoparticles
A nanoparticle drug delivery system designed for brain tumor therapy has shown promising tumor cell selectivity in a novel cell culture model devised by University of Nottingham scientists. view more (2007-08-23)
Little lifesavers — Nanoparticles improve delivery of medicines and diagnostics
Tiny, biodegradable particles filled with medicine may also contain answers to some of the biggest human health problems, including cancer and tuberculosis. The secret is the size of the package. view more (2007-04-11)
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...
