Scrutinizing a single molecule for more than a few milliseconds used to require effectively "stapling" it down, inhibiting its normal behavior. Now, using a technique recently developed in their lab, Stanford chemists have for the first time confined a protein (one involved in photosynthesis), observed its behavior for more than a second and learned things about it that could influence solar energy technology and biofuels. For the first time, researchers have been able to confine and study an...

Efficient identification of drug candidates The search for new therapeutic agents is time-consuming and expensive. Pharmaceutical companies may have to screen thousands of compounds for the ability to bind a target molecule before they hit upon a promising drug candidate. A group of Biophysicists at LMU Munich led by Professor Dieter Braun, a member of the Cluster of Excellence "Nanosystems Initiative Munich" (NIM), and a partner in NanoTemper (an LMU spin-off), have now developed a unique...

Researchers at the Helmholtz Zentrum Mnchen and the Technische Universität Mnchen are using a combination of light and ultrasound to visualize fluorescent proteins that are seated several centimeters deep into living tissue. In the past, even modern technologies have failed to produce high-resolution fluorescence images from this depth because of the strong scattering of light. In the Nature Photonics journal, the Munich researchers describe how they can reveal genetic expression within...
