Mass spectrometry methods database gets major update
Researchers at the National Institute of Standards and Technology (NIST) recently added 150 new methods-nicknamed "recipes"-to a database already containing 255 procedures for analyzing specific synthetic polymers using matrix-assisted laser desorption/ionization (MALDI) mass spectrometry. view more (2006-05-26)
Drug-eluting stents may cause allergic reactions
Drug-eluting stents have greatly reduced the risk of repeat blockage of heart arteries, but researchers from Northwestern Memorial Hospital have found that in some patients, the stents can cause allergic reactions that can have serious consequences. view more (2005-12-20)
Sticky surfaces turn slippery with the flip of a molecular light switch
Changing a surface from sticky to slippery could now be as easy as flipping a molecular light switch. view more (2006-06-20)
Directed self-ordering of organic molecules for electronic devices
A simple surface treatment technique demonstrated by a collaboration between researchers at the National Institute of Standards and Technology (NIST), Penn State and the University of Kentucky potentially offers a low-cost way to mass produce large arrays of organic electronic transistors on polymer sheets for a wide range of applications... view more...

Plastics that convert light to electricity could have a big impact
Researchers the world over are striving to develop organic solar cells that can be produced easily and inexpensively as thin films that could be widely used to generate electricity. view more (2009-08-05)
Researchers prolong the plasma half-life of biopharmaceutical proteins
Many biopharmaceuticals comprise small proteins that are quickly eliminated from the body. Scientists at the Technische Universitaet Muenchen (TUM) combine such small proteins with a kind of molecular balloon that swells and thus prolongs the half-life of the proteins in the body. view more (2009-09-21)
Students' device may improve chest closure after heart surgery
To operate on the heart, surgeons usually cut through the breastbone. After correcting the heart problem, they reconnect the sternum by piercing it with steel wires, pulling the bone segments together and twisting the wires tight. view more (2006-06-07)
Nanoparticle Could Help Detect Many Diseases Early
Most people think of hydrogen peroxide as a topical germ killer, but the medicine cabinet staple is gaining steam in the medical community as an early indicator of disease in the body. view more (2007-08-21)
UCLA researchers develop new method for producing transparent conductors
Researchers at UCLA have developed a new method for producing a hybrid graphene-carbon nanotube, or G-CNT, for potential use as a transparent conductor in solar cells and consumer electronic devices. view more (2009-05-14)
Platinum nanocatalyst could aid drugmakers
Nanoparticles combining platinum and gold act as superefficient catalysts, but chemists have struggled to create them in an industrially useful form. view more (2009-09-01)
Carnegie Mellon scientists develop nanogels that enable controlled delivery of carbohydrate drugs
Carnegie Mellon University scientists have developed tiny, spherical nanogels that uniformly release encapsulated carbohydrate-based drugs. view more (2007-08-21)
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)
Applied scientists create wrinkled 'skin' on polymers
Applied scientists demonstrated a new method for developing wrinkled hard skins on the surface areas of polymers using a focused ion beam. view more (2007-01-17)
Silver is the key to reducing pneumonia associated with breathing tubes
People have long prized silver as a precious metal. Now, silver-coated endotracheal tubes are giving critically ill patients another reason to value the lustrous metal. view more (2008-08-20)
ETH Zurich Develops a Single-chip Microsensor System to Analyse Gases
There are many target application areas envisaged for the gas sensor chip. Air quality in closed rooms can be monitored. The presence of dangerous - even poisonous - substances in the air can be detected, such as benzene from petrol pumps or perchloroethylene from dry-cleaning installations, and warnings can then be issued. Low-cost Mass... view more... (2001-11-14)
An artificial cornea is in sight, thanks to biomimetic hydrogels
If eyes are "the windows of the soul," corneas are the panes in those windows. They shield the eye from dust and germs. They also act as the eye's outermost lens, contributing up to 75 percent of the eye's focusing power. view more (2006-09-12)
Nanomedicine opens the way for nerve cell regeneration
The ability to regenerate nerve cells in the body could reduce the effects of trauma and disease in a dramatic way. In two presentations at the NSTI Nanotech 2007 Conference, researchers describe the use of nanotechnology to enhance the regeneration of nerve cells. view more (2007-05-21)
MIT team building robotic fin for submarines
Inspired by the efficient swimming motion of the bluegill sunfish, MIT researchers are building a mechanical fin that could one day propel robotic submarines. view more (2007-07-31)
Space suit technology can protect workers from heatstroke
The technology used in space suits to protect astronauts carrying out space walks in direct sunlight is now being used to develop protective clothing to safeguard firefighters and steel workers who often work in extremely hot and dangerous conditions. view more (2006-03-06)
New microsensor measures volatile organic compounds in water and air on-site
Researchers at the Georgia Institute of Technology have developed a miniature sensor that uses polymer membranes deposited on a tiny silicon disk to measure pollutants present in aqueous or gaseous environments. view more (2007-09-18)
