We combine biophysical techniques with nanoscopic imaging to study the structure, folding and dynamics of prions, both in isolation and with likely binding partners, in order to develop new strategies against prion diseases. We have developed nanoscopic imaging to observe amyloid structures over extended times through transient amyloid binding (TAB) of dye molecules. The movie shows real time TAB imaging of Aβ42 fibril remodelling over 48 h by the anti-amyloid compound epi-gallocatechin gallate (from: Spehar et al. 2018)
