Molecular torch sheds light on cells

Abstract:
Researchers have created the world's tiniest artificial light source. The nanowire 'torch' may pave the way for remarkably high resolution imaging of individual cells and molecular structures.

The technology is also stable in physiological conditions, overcoming what has so far been a major obstacle to imaging objects at the molecular scale, which are smaller than the wavelength of visible light.

The use of nanowires as a light source has "a wide range of potential applications in physics, chemistry, materials science and biology," said the authors behind the technology in a study published this week in the British journal Nature.
