Study shows nanoshells ideal as chemical nanosensors

'Nanoshells' enhance sensitivity to chemicaldetection by factor of 10 billionNew research published in the Proceedings of the National Academy ofScience finds that tailored nanoparticles known as nanoshells canenhance chemical sensing by as much as 10 billion times. That makesthem about 10,000 times more effective at Raman scattering thantraditional methods. Whenmolecules and materi...

Polymers with copper show promise for implanted sensors

Developing chemical sensors that can be placed in the bloodstream or under the skin to continuously monitor oxygen, acidity (pH), or glucose levels is a major challenge for analytical chemists and biomedical engineers. The problem is, the body responds to these foreign objects in ways that interfere with their ability to accurately measure blood chemistry. In the bloodstream, clots form on the su...

Bad aftertaste? New sensory on/off switch may 'cure' bane of artificial sweetener search

Chemistry and biology researchers at Virginia Tech have enhanced the abilities of the molecules they are creating to deliver killing blows to cancer cells. The man-made molecular complexes enter cancer cells and, when signaled, deliver killing medicine or cause the cell to change. The new supermolecules have more units that will absorb light - providing more control over the range of light freque...

Aptamer-based 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. "The system will provide an increased capa...

Motorola researchers develop selective sensors based on carbon nanotubes

A team of researchers from Arizona State University and Motorola Labs, the applied research arm of Motorola Inc., has developed sensors based on carbon nanotubes, microscopically small structures that posses excellent electronic properties. In early tests, the new devices detected the presence of heavy metal ions in water down to parts per trillion levels. Specifically, the researchers de...

Biosensor chip to help drug development

Infineon in co-operation with the Max Planck Institute, has succeeded in finding a new biosensor chip, called a Neuro-Chip, which researchers claim is a breakthrough technology that will help scientific researchers to gain new insights into the biologic function of neurons, nerve tissue and organic neural networks. Infineon's Neuro-Chip is based on a standard complementary// metal oxide semicondu...

ADHD improvement with sensory intervention

Children suffering from Attention Deficit Hyperactivity Syndrome (ADHD) may now to treated to a better// condition with the help of sensory interventions like applying deep pressure or putting them through strenuous exercise, etc. Attention Deficit Hyperactivity Disorder (ADHD) is a condition that affects nearly 3 to 5 percent of children in pre-school and early school years. Children...

New sensors developed to predict effectiveness of radiotherapy treatment

The human population is exposed to both natural and artificial sources of radiation, which can cause cancer and other defects. Strangely, the same radiation that causes such effects is used for the treatment of cancer, //referred to as radiotherapy. It is however very difficult to assess if the precise dose of radiation is being delivered. New sensor systems have now been developed th...

Discovery of a built-in 'fat sensor'

New research suggests the tongue may have taste sensors dedicated to detecting fat, just as it does for salty, sour, bitter and sweet foods. The study, which appears in the November issue of the Journal of Clinical Investigation,// suggests that rats and mice exhibit a spontaneous attraction for lipids. Such a behavior raises the possibility that an orosensory system is responsible for...

New Sensor Created For Lung Disorder Patients

South Korean scientists have created a non-invasive sensor that will help treat patients with chronic obstructive pulmonary disease.// When a patient faces respiratory distress in the emergency room doctors usually administer high concentrations of oxygen via a mask. But for some people with chronic obstructive pulmonary disease it can actually shut down the body's breathing reflex....
