How to track and trace a protein: Nanosensors monitor intracellular deliveries
(PHYSorg.com Nanotechnology)

Researchers at the University of Basel`s Biozentrum have developed a method for tracing the movement of proteins within the cell. They tagged proteins with tiny nanosensors, so-called nanobodies, which enable the scientists to live track and trace the proteins` pathway through the cell. The method described in the current issue of PNAS is suitable for a wide range of research purposes.
