Researchers at Oregon State University have tapped into the extraordinary power of carbon “nanotubes” to increase the speed of biological sensors, a technology that might one day allow a doctor to routinely perform lab tests in minutes, speeding diagnosis and treatment while reducing costs.
The new findings have almost tripled the speed of prototype nano-biosensors, and should find applications not only in medicine but in toxicology, environmental monitoring, new drug development and other fields.
The research was just reported in Lab on a Chip, a professional journal. More refinements are necessary before the systems are ready for commercial production, scientists say, but they hold great potential.
Artificial lung mimics real organ functionsBS Reporter / July 27, 2011, 0:21 IST
An artificial lung built by Cleveland researchers has accounted for functions akin to the genuine organ, while using air—not pure oxygen as current artificial lungs require.
People from BioMEMS research group @ University of auckland stated that

[Epub ahead of print])provides an innovative summary of the recent advances in miniaturized chip-based devices for the analysis of programmed cell death.it provides future prospects of the Lab-on-a-Chip devices with wide reaching perspectives in anti-cancer drug discovery and high-throughput cell-based screening routines.
Researchers have invented a technique that uses inexpensive paper to make “microfluidic” devices for rapid medical diagnostics and chemical analysis.
Colored water is used to show how liquid wicks along tiny channels formed in paper using a laser, in research to develop a new technology for medical diagnostics and chemical analysis. Silica microparticles were deposited on patterned areas, allowing liquid to diffuse from one end of a channel to the other. (Birck Nanotechnology Center, Purdue University)
The innovation represents a way to enhance commercially available diagnostic devices that use paper-strip assays like those that test for diabetes and pregnancy.
