Ein Besen aus Licht soll Farblaser billiger machen

Was Silizium fuer die Entwickler von Computerchips, ist fuer Laserphysiker eine Substanz namens Lithiumniobat. Diese Stellung verdanken die durchsichtigen Kristalle vor allem einer schoenen Eigenschaft: Sie koennen die Farbe von Laserlicht veraendern. Dazu muessen sie allerdings ausreichend sauber sein. Und diese Reinigung war bislang ein schwieriges und teures Unterfangen. Forscher um den Bonner Physiker Professor Dr. Karsten Buse konnten freien Elektronen nun mit einem Besen aus Licht aus dem Kristall kehren.

Antibody replacements just a 'click' away

Chemists at the California Institute of Technology (Caltech) and The Scripps Research Institute (SRI) have developed an innovative technique to create cheap but highly stable chemicals that have the potential to take the place of the antibodies used in many standard medical diagnostic tests.

Accoustic tweezers to place nano-objects

Manipulating tiny objects like single cells or nanosized beads often requires relatively large, unwieldy equipment, but now a system that uses sound as a tiny tweezers can be small enough to place on a chip, according to Penn State engineers.
