In an important step toward performing medical diagnoses using handheld devices, the researchers have adapted silicon chip technology similar to that found in personal computers and mobile phones to function as a biosensor. The technology uses tiny metal layers embedded...

Boston University project helps reveal complex brain functions in living animals. Microscopy platforms able to monitor large populations of cells in living specimens are increasingly vital for understanding neuronal activity, but scanning microscope technologies with micron-scale resolution can be slow...

New photonic tools for medical imaging can be used to understand the nonlinear behavior of laser light in human blood for theranostic applications. When light enters biological fluids it is quickly scattered, however, some cell suspensions can induce nonlinear responses...

Researchers at Swinburne University of Technology (Hawthorn, VIC, Australia), the University of Sydney (Sydney, NSW, Australia), and Australian National University (Canberra, ACT, Australia) have collaborated to develop a solar absorbing, ultrathin graphene-based film with unique properties that has great potential...

Combining multiple photonic imaging techniques could allow for new, noninvasive approaches to tumor detection and assessment, meeting clinical challenges at a time of rising global cancer incidence. Aging populations, exposure to environmental contamination in developing countries, and other factors are...

A new way of measuring atomic-scale magnetic fields with great precision, not only up and down but sideways as well, has been developed by researchers at MIT. The new tool could be useful in applications as diverse as mapping the...

A team of scientists from Helmholtz Zentrum München, the Jülich Research Center, the Technical University of Munich, and Heinrich Heine University Düsseldorf (all in Germany) has shown that harmless purple bacteria of the genus Rhodobacter are capable of visualizing aspects...

Using novel nanofabrication techniques, researchers from the University of Pennsylvania and Cornell University have built micro-robots made from silicon and powered by solar cells. One million functional microscopic robots can be produced from a 4-in. silicon wafer. The robots’ bodies...

There’s an entire world our eyes miss, hidden in the ranges of light wavelengths that human eyes can’t see. But infrared cameras can pick up the secret light emitted as plants photosynthesize, as cool stars burn and batteries get hot....

Not all cancerous tumors respond equally to treatments and therapy, which complicates treatment regimes for clinicians and outcomes for patients. A project at the University of Arkansas and Johns Hopkins University has now used Raman spectroscopy to reveal differences between...
