More precise food-allergy diagnoses

(PhysOrg.com) -- About 30 percent of Americans believe they have food allergies. However, the actual number is far smaller, closer to 5 percent, according to a recent study commissioned by the National Institute of Allergy ...

A nanoscale window to the biological world

If the key to winning battles is knowing both your enemy and yourself, then scientists are now well on their way toward becoming the Sun Tzus of medicine by taking a giant step toward a priceless advantage – the ability ...

Radical research changes lab-on-a-chip design

(PhysOrg.com) -- A University of Alberta mechanical engineering professor has developed a new model that could revolutionize the design of hand-held devices that provide reliable, nearly instant medical or environmental tests.

The laser beam as a "3D painter"

(Phys.org)—There are many ways to create three dimensional objects on a micrometer scale. But how can the chemical properties of a material be tuned at micrometer  precision? Scientists at the Vienna University of Technology ...

Lab-on-a-chip helps search for human DNA at crime scenes

Thanks to the work carried out by University of Twente Ph.D. candidate Brigitte Bruijns, crime scenes can now be inspected on the spot for the presence of human DNA. In her Ph.D. thesis, she describes a lab-on-a-chip that ...

New technique controls fluids at the nanoscale

(Phys.org) —Researchers at Swinburne University of Technology have revealed a revolutionary method of pumping fluid at the nanoscale level that has potential use for desalinating water and lab-on-a-chip devices.

Sensor biochips could aid in cancer diagnosis and treatment

It is very difficult to predict whether a cancer drug will help an individual patient: only around one third of drugs will work directly in a given patient. Researchers at the Heinz Nixdorf Chair for Medical Electronics at ...
