Photonic plasmon hook: scientists obtain a new class of curved beams for biosensors and nanoparticle control

A new class of curved plasmon beams named as a photonic hook plasmon can be used as a nanoparticle manipulator, as well as in biosensors to study substances in small volumes and plasmon microscopes for benefiting superresolution.

A self-powered heart monitor taped to the skin

Scientists have developed a human-friendly, ultra-flexible organic sensor powered by sunlight, which acts as a self-powered heart monitor.

Scientists create new oil-resistant filter technology (w/video)

The new invention consists of a type of coating that produces thin films of water-loving, oil-repelling molecules on the surface of filter membranes. These metal oxide molecules grab onto any loose water atoms while resisting oil.

Spinning the light: The world's smallest optical gyroscope

Engineers create an optical gyroscope smaller than a grain of rice.

Study breaks Förster resonant energy transfer (FRET) distance limit

Using engineered nanocomposite structures called metamaterials, a research team reports the ability to measure a significant increase in the energy transfer between molecules.

Nanotubes may give the world better batteries

Scientists' method quenches lithium metal dendrites in batteries that charge faster, last longer.

Light-bending tech shrinks kilometers-long radiation system to millimeter scale

The DESY accelerator facility in Hamburg, Germany, goes on for miles to host a particle making kilometer-long laps at almost the speed of light. Now researchers have shrunk such a facility to the size of a computer chip.
