Analysing single-molecule fluorescence resonance energy transfer (smFRET) enables an unprecedented view of the dynamics and kinetics of biomolecular conformational changes and interactions. In this Primer, Ha et al. discuss technological advances that have led to smFRET and how the method can be adapted to address various research questions in structural and molecular biology.
