Die Firma CS-Chromatographie Service wird in den kommenden zwei Jahren gemeinsam mit dem Forschungszentrum Juelich und der Firma Chemical Consulting Dornseiffer (CCD) untersuchen, wie Nanopartikel in der Analytik eingesetzt werden koennen, um bekannte chromatographische Trennverfahren zu verbessern.
Using new technology that allows scientists to monitor how individual cells react in the complex system of cell signaling, Stanford University researchers have uncovered a much larger spectrum of differences between each cell than ever seen before.
A cluster of carbon nanotubes coated with a thin layer of protein-recognizing polymer form a biosensor capable of using electrochemical signals to detect minute amounts of proteins, which could provide a crucial new diagnostic tool for the detection of a range of illnesses.
Das Bundesministerium fuer Bildung und Forschung foerdert ein Verbundprojekt zur Sicherheit von Arbeitsplaetzen in der Nanotechnik im Rahmen seines Programms NanoCare jetzt mit mehr als einer halben Million Euro.
At a snail's pace - this is how proteins should move inside living cells where viscosity of environment exceeds the viscosity of water even by million times. However, proteins move not much slower than in water! While looking for a solution to this puzzle, scientists from the Institute of Physical Chemistry of the PolishAcademy of Sciences discovered a new principle of physics.
Metallic glasses are - just as other types of glasses- brittle materials. This property sets a limit to the possibilities of their technical use. Researchers have now developed a mechanism that enables metallic glasses to become ductile under tensile loading.
Until now, it has been assumed that during photoemission the electron start moving out of the atom immediately after the impact of the photon. This point in time can be detected and has so far been considered as coincident with the arrival time of the light pulse, i.e. with 'time zero' in the interaction of light with matter. Using their ultra-short time measurement technology, physicists have now tested this assumption.
Researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University, Harvard Medical School and Children's Hospital Boston have created a device that mimics a living, breathing human lung on a microchip. The device, about the size of a rubber eraser, acts much like a lung in a human body and is made using human lung and blood vessel cells.
EUREKA project E! 3371 Gene Transfer Agents has made great advances in the development of novel non-viral carriers able to introduce genetic material into the target cells. These new agents, derivatives of cationic amphiphilic 1,4-dihydropyridine (1,4-DHP), avoid the problems of the recipient's immune system reacting against a viral carrier.
