Abstract
To overcome the photobleaching problem inherent to fluorescence techniques we recently developed a new optical detection method for individual non-fluorescent nano-objects. It allows detecting the movement of individual membrane proteins labeled with 5 nm gold nanoparticles in living cells for arbitrary long times.
