New way to funnel light could have infrared applications

(PhysOrg.com) -- Taking light control to a new level, scientists have proposed a technique for confining light into an area just 1/500th the size of the light's wavelength. Since funneling light through such tiny spaces enhances ...

Flexible silicon solar-cell fabrics may soon become possible

For the first time, a silicon-based optical fiber with solar-cell capabilities has been developed that has been shown to be scalable to many meters in length. The research opens the door to the possibility of weaving together ...

Blocked holes can enhance rather than stop light going through

Conventional wisdom would say that blocking a hole would prevent light from going through it, but Princeton University engineers have discovered the opposite to be true. A research team has found that placing a metal cap ...

In situ extraction and detection of DNA using nanopores

Being able to detect DNA from a single cell is important for the detection of diseases and genetic disorders. Measuring single DNA molecules has been possible for some time; however, directly detecting samples at the point ...

New insights into early embryonic development

The majority of pregnancies that fail do so at a very early developmental stage, before the pregnancy is even detectable by tests. This critical stage, occurring about a week after fertilization, is when an embryo implants ...

The holy grail of nanowire production

Nanowires have the potential to revolutionize the technology around us. Measuring just 5-100 nanometers in diameter (a nanometer is a millionth of a millimeter), these tiny, needle-shaped crystalline structures can alter ...
