While refining their novel method for making nanoscale wires, chemists at the National Institute of Standards and Technology (NIST) discovered an unexpected bonus"”a new way to create nanowires that produce light similar to that from light-emitting diodes (LEDs). These "nano-LEDs" may one day have their light-emission abilities put to work serving miniature devices such as nanogenerators or lab-on-a-chip systems.Nanowires typically are "grown" by the controlled deposition of...

Researchers at Oregon State University have reported the successful loading of biological molecules onto "nanosprings" "“ a type of nanostructure that has gained significant interest in recent years for its ability to maximize surface area in microreactors. The findings, announced in the journal Biotechnology Progress, may open the door to important new nanotech applications in production of pharmaceuticals, biological sensors, biomedicine or other areas. "Nanosprings are a fairly new...

Researchers at the National Institute of Standards and Technology (NIST) have demonstrated a microminiaturized device that can make complex viscosity measurements"”critical data for a wide variety of fields dealing with things that have to flow"”on sample sizes as small as a few nanoliters. Currently a table-top prototype, the NIST rheometer could be a particularly valuable tool for biotechnologists studying minute quantities of complex materials that must function in confined...

A wrench or a screwdriver of a single size is useful for some jobs, but for a more complicated project, you need a set of tools of different sizes. Following this guiding principle, researchers at the National Institute of Standards and Technology (NIST) have engineered a nanoscale fluidic device that functions as a miniature "multi-tool" for working with nanoparticles"”objects whose dimensions are measured in nanometers, or billionths of a meter. First introduced in March 2009 (see...

Microfluidic device uses antibodies to 'capture' white blood cells called T cells affected by HIV UC Davis biomedical engineer Prof. Alexander Revzin has developed a "lab on a chip" device for HIV testing. Revzin's microfluidic device uses antibodies to "capture" white blood cells called T cells that are affected by HIV. In addition to physically binding these cells the test detects the types and levels of inflammatory proteins (cytokines) released by the cells. Revzin's team collaborated...

Using new technology that allows scientists to monitor how individual cells react in the complex system of cell signaling, Stanford University researchers have uncovered a much larger spectrum of differences between each cell than ever seen before. Cells don't all act in a uniform fashion, as was previously thought. "Think of cells as musicians in a jazz band," said Markus Covert, PhD, assistant professor of bioengineering and senior author of the study, which will be published online in...

With "hands-on" experiences in childhood and adolescence having sparked so many science careers, scientists in Canada are describing a quick, simple, safe, and inexpensive way for kids to participate in making microfluidic devices. Those devices are at the heart of lab-on-a chip, inkjet printing, DNA chip, and other technologies. The scientists' instructions for making microfluidic devices from Jell-O® type dessert mixes and Popsicle-type sticks, and using them to...

Researchers at Purdue University have developed a potential new tool for medical diagnostics, testing food and water for contamination, and crime-scene forensics. The technique uses a combination of light and electric fields to position droplets and tiny particles, such as bacteria, viruses and DNA, which are contained inside the drops. Other methods using either light or electric fields separately are able to position droplets or the particles they contain, but the new "hybrid optoelectric"...

Each year, about 80,000 people in Germany become seriously ill from occlusions of veins caused by blood clots. Such thromboses can cause pulmonary embolism or even heart attacks. Even airline passengers at long distance flights can be affected by deep vein thrombosis. But with the new system, a fast and easy test of a risk of travel-related thrombosis will soon be possible. Airline passengers would only have to relinquish one drop of blood to the measuring device. The special feature of this...

UC engineering researchers create tiny pools without walls with programmable microfluidic systems Microfluidic devices typically depend upon electrokinetic or traditional pressure methods to move microscopic amounts of fluid around a fixed microchip. As just published as the cover story in "Lab on a Chip," in "Virtual electrowetting channels: electronic liquid transport with continuous channel functionality," engineering researchers at the University of Cincinnati have created a paradigm...
