Miniaturized lasers can emit quantum light

The discovery of this quantization of the light field has opened up a new field of physics - quantum optics. In modern lasers the light emission can take place within a picosecond, a 1000 times faster than has ever been detected before in photon sequence measurements. A team in Germany made a major breakthrough: in several years of work the worldwide first detector has been developed which has the necessary temporal resolution.

Dye-doped DNA nanofibers emit white light

A team of researchers at the University of Connecticut and the US Air Force Research Laboratory has now successfully used the electrospinning of DNA complexes to produce nanofibers that incorporate two different fluorescing dyes in such a way that energy can efficiently be transferred from one dye to the other. The color of the resulting fluorescence can be controlled by means of the ratio of the two dyes.

Filling fullerenes with radio-active material for radiation therapy

Virginia Tech chemistry Professor Harry C. Dorn, Emory and Henry College chemistry Professor James Duchamp, and Panos Fatouros, professor and chair of the Division of Radiation Physics and Biology at the Virginia Commonwealth University School of Medicine have co-invented a hands-off process for filling fullerenes with radio-active material.
