Scientists invent long-lasting, near infrared-emitting material

Materials that emit visible light after being exposed to sunlight are commonplace and can be found in everything from emergency signage to glow-in-the-dark stickers. But until now, scientists have had little success creating ...

Faster diagnostics through cheap, ultra-portable blood testing

Blood tests are important diagnostic tools. They accurately tease-out vanishingly small concentrations of proteins and other molecules that help give a picture of overall health or signal the presence of specific diseases. ...

Detecting the Undetectable in Prostate Cancer Testing

(PhysOrg.com) -- A team of Northwestern University researchers, using an extremely sensitive nanotechnology-based tool known as the biobarcode system, has detected previously undetectable levels of prostate-specific antigen ...

Microchip can detect type and severity of cancer

(PhysOrg.com) -- University of Toronto 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 ...

Breath or urine analysis may detect cancer, diabetes

(PhysOrg.com) -- A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing ...

New genre of sugar-coated 'quantum dots' for drug delivery

(PhysOrg.com) -- Scientists in Switzerland are reporting an advance that could help tap the much-heralded potential of “quantum dots”— nanocrystals that glow when exposed to ultraviolet light — in the treatment of ...
