New micro instrument controls medicine flows
Research scientists at the Micro and Nanotechnology Laboratory in Oslo have developed a flow metre with fluid channels thinner than a strand of hair. The new device controls that patients receive the correct dosage of medicine. view more (2004-11-03)
Tiny 'Lab-on-a-Chip' Can Detect Pollutants, Disease and Biological Weapons
For centuries, animals have been our first line of defense against toxins. A canary in a coalmine served as a living monitor for poisonous gases. Scientists used fish to test for contaminants in our water. Even with modern advances, though, it can take days to detect a fatal chemical or organism. view more (2009-02-18)
RC-LEDs - Super-fast light sources suitable for data transfer
Resonance-cavity light-emitting diodes (RC-LEDs) are a new type of light source which produces very intense light from quantum wells located in a microcavity. As light sources, RC-LEDs are classified as something between laser diodes and conventional light-emitting diodes (LEDs). The advantages of RC-LEDs compared with conventional LEDs include a... view more... (2000-02-25)
Nanotubes used for first time to send signals to nerve cells
Texas scientists have added one more trick to the amazing repertoire of carbon nanotubes - the ability to carry electrical signals to nerve cells. view more (2006-05-09)
Iowa State scientists demonstrate first use of nanotechnology to enter plant cells
A team of Iowa State University plant scientists and materials chemists have successfully used nanotechnology to penetrate plant cell walls and simultaneously deliver a gene and a chemical that triggers its expression with controlled precision. view more (2007-05-17)
Designer Isotopes Push the Frontier of Science

Needle-size device created to track tumors, radiation dose
Engineers at Purdue University are creating a wireless device designed to be injected into tumors to tell doctors the precise dose of radiation received and locate the exact position of tumors during treatment. view more (2008-04-09)
Engineers point way to better use of nanotubes as measuring tips
Engineers at Purdue University have shown how researchers might better use tiny hollow fibers called "multi-walled carbon nanotubes" to more precisely measure structures and devices for electronics and other applications. view more (2005-10-13)
Researchers effectively treat tumors with use of nanotubes
By injecting man-made, microscopic tubes into tumors and heating them with a quick, 30-second zap of a laser, scientists have discovered a way to effectively kill kidney tumors in nearly 80 percent of mice. view more (2009-08-04)
Nanomanufacturing: Systematic study of nanostructure growth yields production 'road map'
Researchers have taken an important step toward high-volume production of new nanometer-scale structures with the first systematic study of growth conditions that affect production of one-dimensional nanostructures from the optoelectronic material cadmium selenide (CdSe). view more (2005-11-01)
Nanoparticle Assembly Enters the Fast Lane
The speed of nanoparticle assembly can be accelerated with the assistance of the molecule that carries life's genetic instructions, DNA, a team of researchers at the U.S. Department of Energy's Brookhaven National Laboratory recently found. view more (2006-10-12)
The gold standard: Biodesign Institute researchers use nanoparticles to make 3-D DNA nanotubes
Arizona State University researchers Hao Yan and Yan Liu imagine and assemble intricate structures on a scale almost unfathomably small. Their medium is the double-helical DNA molecule, a versatile building material offering near limitless construction potential. view more (2009-01-05)
A new 'Pyrex' nanoparticle
Researchers in Switzerland have developed a new method to fabricate borosilicate glass nanoparticles. Used in microfluidic systems, these "Pyrex"-like nanoparticles are more stable when subjected to temperature fluctuations and harsh chemical environments than currently used nanoparticles made of polymers or silica glass. view more (2008-09-08)
U of T researchers create microchip that can detect type and severity of cancer
U of T researchers have used nanomaterials to develop a microchip sensitive enough to quickly determine the type and severity of a patient's cancer so that the disease can be detected earlier for more effective treatment. view more (2009-09-28)
Smallest Nanoantennas for High-speed Data Networks
More than 120 years after the discovery of the electromagnetic character of radio waves by Heinrich Hertz, wireless data transmission dominates information technology. view more (2009-10-21)
Mathematicians maximize knowledge of minimal surfaces
Mathematicians have studied basic minimal surfaces for more than 250 years, and long ago understood their basic building blocks and how those fundamentals fit together to form a figure with the least surface area and high surface tension. view more (2006-08-16)
