A Cluster for the Development of Dynamic 3D Nanoscopy (360G-Wellcome-203285_C_16_Z)

Imagine if we could watch multiple molecules in living cells as they move and interact. This dream may seem years away, but it is now realistic to achieve real-time dynamic super-resolution imaging of multiple tagged proteins in three dimensions (3D) in cells and in tissues. This will allow biologists to discover large-scale patterns involving diverse structures including transport vesicles, ribosomes, and chromatin domains, all previously inaccessible because they lie in the gap between the resolution of electron (1- 2 nm) and light microscopy (200-300 nm). The "big picture" of cellular organization/information processing would emerge, with advances in understanding cell function in health and disease. While we can now do this in 2D, 3D imaging is needed to follow objects as they move out of the plane. Achieving 3D imaging is a major challenge and will require two orders of magnitude more information per cellular volume, and novel algorithms to classify, analyze, and visualize patterns from massive datasets. We propose specific innovations (Table 1) that, should allow us to achieve this over the next five years, given our team’s proven track record of success.
