Electronic nose detects pneumonia
British scientists have developed an electronic nose capable of identifying potentially-fatal strains of pneumonia by "smelling" a patient’s breath. ... Continue Reading
Biosensor offers rapid disease diagnosis
European researchers have unveiled new biosensor technology that could help doctors to diagnose diseases such as cancer, heart disease, and multiple sclerosis in just 15 minutes. ... Continue Reading
A Biosensor Layered Like Lasagna
In a mixing of pasta metaphors, Pacific Northwest National Laboratory scientists have used electrostatic attraction to layer reactive biological molecules lasagna-like around spaghetti-like carbon nanotubes. The configuration can accommodate a wide range of applications, from ultra-precise blood-sugar monitoring to infectious-agent detection, said Yuehe Lin, who led the research at the Department of Energy campus ...

Building A Hand-held Lab-on-a-chip To Simplify Blood Tests
A cell phone-sized blood-count machine requiring less blood than a mosquito bite will make blood tests easier for many patients, from neonatal units to astronauts in space. ... Continue Reading
Toxicology-on-a-chip Tool Readies For Market
Recalls of popular prescription drugs are raising public concern about the general safety of new pharmaceuticals. A collaborative group of researchers says that identifying which drug candidates are toxic early in the discovery process can help prevent harmful pharmaceuticals from being placed on the market in the first place, and they have developed a tool to do it. ...

E-nose to sniff out hospital superbugs
AN ELECTRONIC nose that sniffs out infections could help hospitals tackle outbreaks of the antibiotic-resistant superbug MRSA. Culture tests routinely used to identify MRSA (methicillin-resistant Staphylococcus aureus ) take two or three days to complete. This hampers attempts to manage outbreaks as infected patients remain untreated and at risk of infecting others. ... Continue Reading
New tiny sensors spot disease before it occurs.
When doctors need to peek at mysterious goings-on inside the human body, they can skip the scalpel and rely on MRIs and CT scans. These state-of-the-art imaging technologies, successors to the X ray, reveal exquisitely detailed pictures of various tissues, organs and other anatomy. ... Continue Reading
'Biosensor' Screens Air Force Personnel And Equipment
Air Force personnel will soon know within minutes if they or their equipment are contaminated with a biological agent, thanks to a new technology developed by the Air Force and a national laboratory.Personnel will use the biosensor system to collect and isolate samples, detect and identify agents, and assess the seriousness of the threat. ...

How Scanning Your Finger Could Save Your Life
Who would have thought taking a simple scan of your finger could save your life? Unlikely on the face of it, perhaps, but a consortium including Cranfield Impact Centre and Nissan Technical Centre Europe, has developed a prototype bone density scanning system which could be used to improve driver and passenger restraint systems in cars. ...

Molecular Thermometers On Skin Cells Detect Heat And Camphor
The human brain is like a general in a bunker. Floating in its bubble of cerebrospinal fluid, it has no direct window to the outside world, so the only way for the brain to observe, comprehend, and order the body into action is to rely on information it receives. This information comes to it through a sophisticated system of sensory neurons that connect the brain to organs like the eye, ear, nose, and mouth. ... Continue Reading
