Can biophysical approaches really shed light into the research on membrane biological processes? Are those approaches too simplified to describe the real cellular event? Emerging nano-technology and single-molecule study are fundamentally shaking such a skeptical viewpoint. Structures fabricated at the nanoscale and the novel FRET imaging technique provide a unprecedented avenue for controlling and illuminating membrane biological processes at the innate length scale, the nanometer range. Here I report two novel examples; control of membrane molecule dynamics using nano-topographic structures, and real-time imaging of SNARE protein-driven membrane fusion at the single event level. Taking one step further, I will dissect the previously elusive function of two membrane fusion regulators and then, report the first reconstitution of the core neuron-signaling machinery; Ca2+-triggered synchronized membrane fusion events. This study could demonstrate how biophysical approaches address and answer the contemporary questions that biologists really want to know."
