B11 - Nanoscale observations of membrane dynamics

The lipid composition of biological membranes, along with its spatial organization and temporal dynamics, are acknowledged to be fundamental to cellular and protein functionality. However, techniques for observing membrane heterogeneity are often limited in terms of spatial and temporal resolution or influence on the system under study. Here, we use the superior spatio-temporal resolution of STED microscopy and fast single-molecule tracking to determine how molecular interactions of the membrane may coalesce into signaling platforms.
