Photonic crystals: 'even thin is functional'

Photonic crystals are the nanostructures that can manipulate photons by means of an energy gap, similar to how the semiconductors in computer chips manipulate electronic current. It was always thought that photonic crystals ...

Terahertz radiation can disrupt proteins in living cells

Researchers from the RIKEN Center for Advanced Photonics and collaborators have discovered that terahertz radiation, contradicting conventional belief, can disrupt proteins in living cells without killing them.

New technique takes 3-D imaging an octave higher

A collaboration between Colorado State University and University of Illinois at Urbana-Champaign resulted in a new, 3-D imaging technique to visualize tissues and other biological samples on a microscopic scale, with potential ...

Geometry of intricately fabricated glass makes light trap itself

Laser light traveling through ornately microfabricated glass has been shown to interact with itself to form self-sustaining wave patterns called solitons. The intricate design fabricated in the glass is a type of "photonic ...

A non-destructive method of analysing molecules in cells

When investigating how tumors grow, or how pharmaceuticals affect different types of cells, researchers have to understand how molecules within a cell react—and interact. This is possible with modern laser microscopy. Until ...
