A laminar flow mixing microfluidic device enables single-molecule fluorescence resonance energy transfer (FRET) kinetic measurements with a time resolution of 0.2 ms, enabling the study of early binding-coupled folding and unfolding events of an intrinsically disordered protein, α-synuclein. Also in this issue, Kim et al. describe another microfluidic mixing device for single-molecule experiments.
