Bio-inspired assembly of nanoparticle building blocks
Chemists at Rice University have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature's oldest known chemical innovations - the self-assembly of lipid membranes that surround every living cell.   view more (2006-11-28)

New nanolaser key to future optical computers and technologies
Because the new device, called a "spaser," is the first of its kind to emit visible light, it represents a critical component for possible future technologies based on "nanophotonic" circuitry, said Vladimir Shalaev, the Robert and Anne Burnett Professor of Electrical and Computer Engineering at Purdue University.   view more (2009-08-17)

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)

UBC researchers put a new spin on electrons
In the first demonstration of its kind, researchers at the University of British Columbia have controlled the spin of electrons using a ballistic technique--bouncing electrons through a microscopic channel of precisely constructed, two-dimensional layer of semiconductor.   view more (2009-04-16)

Special gold nanoparticles show promise for 'cooking' cancer cells
Researchers are describing a long-awaited advance toward applying the marvels of nanotechnology in the battle against cancer. They have developed the first hollow gold nanospheres - smaller than the finest flecks of dust - that search out and "cook" cancer cells.   view more (2009-03-23)

Engineering Nanoparticles for Maximum Strength
Because they are riddled with defects, bulk crystalline materials never achieve their ideal strength; nanocrystals, on the other hand, are so small there's no room for defects.   view more (2008-10-21)

New windows opened on cell-to-cell interactions
Applying biological molecules from cell membranes to the surfaces of artificial materials is opening peepholes on the very basics of cell-to-cell interaction.   view more (2009-07-23)

New source of multipotent adult stem cells discovered in human hair follicles
Researchers at the University of Pennsylvania School of Medicine have isolated a new source of adult stem cells that appear to have the potential to differentiate into several cell types.   view more (2006-07-13)

Blacksmith’s secret revealed
In an international study into the fine structure of steel, Technology Foundation STW researchers have revealed how strong steel is formed. By analysing red-hot steel with an x-ray microscope, the researchers discovered how at a temperature of 900 oC, numerous microscopic crystals suddenly developed in the steel. The findings were published in the... view more... (2002-11-15)

Genetic testing?
Frequently, autopsy becomes the principal diagnostic tool when macro and microscopic analyses provide a conclusive diagnosis in cardiomyopathies.   view more (2008-09-02)

Findings show nanomedicine promising for treating spinal cord injuries
Researchers at Purdue University have discovered a new approach for repairing damaged nerve fibers in spinal cord injuries using nano-spheres that could be injected into the blood shortly after an accident.   view more (2009-11-09)

Bacterial 'switch gene' regulates how oceans emit sulfur into atmosphere
Scientists have discovered a bacterial "switch gene" in two groups of microscopic plankton common in the oceans. The gene helps determine whether certain marine plankton convert a sulfur compound to one that rises into the atmosphere, where it can affect the earth's temperature, or remain in the sea, where it can be used as a nutrient.   view more (2006-10-30)

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)

One-Touch Pathology Slide Microscanning
In clinical pathology the diagnostic process is a multi-step process where the pathologist views a prepared tissue sample on an optical microscope. The pathologist switches repeatedly between a low magnification, wide field view of the whole sample to a high magnification, narrow field view of selected portions of the sample. A diagnosis is made... view more... (2004-02-19)

Environmentally 'green' beer: Munich brewing engineers research energy savings
A cool, freshly drawn beer - for many a person this is the greatest of pleasures. But, in fact, a bad conscience should haunt us when we drink beer as it is among the most energy-intensive foodstuffs during production.   view more (2009-09-08)

A Penn physics study: Of traffic jams, beach sands and the zero-temperature jamming transition
Researchers in condensed matter physics at the University of Pennsylvania and the University of Chicago have created an experimental and computer model to study how jamming, the physical process in which collections of particles are crammed together to behave as solids, might affect the behavior of systems in which thermal motion is important,... view more...

Platinum nanocrystals boost catalytic activity for fuel oxidation, hydrogen production
A research team composed of electrochemists and materials scientists from two continents has produced a new form of the industrially-important metal platinum: 24-facet nanocrystals whose catalytic activity per unit area can be as much as four times higher than existing commercial platinum catalysts.   view more (2007-05-04)

Tiny capsules deliver
A tiny particle syringe composed of polymer layers and nanoparticles may provide drug delivery that targets diseased cells without harming the rest of the body, according to a team of chemical engineers. This delivery system could be robust and flexible enough to deliver a variety of substances.   view more (2009-01-13)

New Electrostatic-based DNA Microarray Technique Could Revolutionize Medical Diagnostics
The dream of personalized medicine - in which diagnostics, risk predictions and treatment decisions are based on a patient's genetic profile - may be on the verge of being expanded beyond the wealthiest of nations with state-of-the-art clinics.   view more (2008-07-01)

New research finds markers for esophageal cancer before it develops
Rhode Island Hospital researchers have identified genetic proteins, also known as biomarkers, capable of distinguishing changes at the microscopic level that can signal a precancerous condition in the esophagus.   view more (2008-11-04)
