live cell imaging

Sunday 30 November 2003

In 1873, Ernst Abbe discovered that features closer than approximately 200 nm cannot be resolved by lens-based light microscopy.

Super-resolution imaging

In recent years, however, several new far-field super-resolution imaging techniques have broken this diffraction limit, producing, for example, video-rate movies of synaptic vesicles in living neurons with 62 nm spatial resolution.

Current research is focused on further improving spatial resolution in an effort to reach the goal of video-rate imaging of live cells with molecular (1-5 nm) resolution.
