Aluminum nanoparticles could improve electronic displays

Whether showing off family photos on smartphones or watching TV shows on laptops, many people look at liquid crystal displays (LCDs) every day. LCDs are continually being improved, but almost all currently use color technology ...

Researchers design and patent graphene biosensors

The Moscow Institute of Physics and Technology (MIPT) is patenting biosensor chips based on graphene, graphene oxide and carbon nanotubes that will improve the analysis of biochemical reactions and accelerate the development ...

Tracking nanowalkers with light

Nanotechnology is taking its first steps. Researchers from the Max Planck Institute for Intelligent Systems in Stuttgart have developed a gold nanocylinder equipped with discrete DNA strands as 'feet' that can walk across ...

New device converts DC electric field to terahertz radiation

Terahertz radiation, the no-man's land of the electromagnetic spectrum, has long stymied researchers. Optical technologies can finagle light in the shorter-wavelength visible and infrared range, while electromagnetic techniques ...

Degrading BPA with visible light and a new hybrid photocatalyst

Over the course of the last half century, BPA has gone from miracle to menace. Its popularity soared after the 1950s, when scientists discovered that it could be used to make polycarbonate plastic—a hard, durable, and transparent ...

A graphene-based sensor that is tunable and highly sensitive

Many areas of fundamental research are interested in graphene owing to its exceptional characteristics. It is made of one layer of carbon atoms, which makes it light and sturdy, and it is an excellent thermal and electrical ...

Could your smartphone one day tell you you're pregnant?

Researchers at the Hanover Centre for Optical Technologies (HOT), University of Hanover, Germany, have developed a self-contained fiber optic sensor for smartphones with the potential for use in a wide variety of biomolecular ...
