 | In biology, as in construction, it's all about having tools that fit the job. Researchers at Rockefeller University have now created a tiny tool, more than 10,000 times smaller than the diameter of a human hair, capable of encasing single membrane proteins from living cells. The new system, which resembles a nanoscale sushi roll, will allow investigators to individually stimulate these key proteins with specific molecules and signals in order to precisely define the biological reactions that result. ...> Full Article |
