Abstract

A rationally designed supramolecular FRET pair consisting of cyanine3-cucurbit[7]uril (Cy3-CB[7]) and boron-dipyrromethene 630/650-adamantylammonium (BDP-AdA) can be used to visualize organelle-specific Autophagy events. The intracellular accumulations of Cy3-CB[7] in lysosomes and BDP-AdA in lipid droplets (LDs) and the formation of an intracellular host-guest complex between Cy3-CB[7] and BDP-AdA resulting in FRET signals allow us to visualize the fusion of LDs with lysosomes, namely, lipophagy. This study demonstrates the potential of supramolecular imaging based on bio-orthogonal host-guest interactions in the investigation of selective Autophagy events.
