Complex colloids consisting of hydrocarbon and fluorocarbon phases are of great interest due to their tunable morphology. Herein, we reported luminescent complex colloids incorporating amphiphilic green fluorescence protein chromophore (GFPc) in hydrocarbon phase. The morphology of colloids changes in response to surfactant variation, and this change leads to luminescence switch. The fluorescence of GFPc is quenched because of water-induced hydrogen bonding. The fluorescence intensities and confocal images of different morphologies were reported. Hydrophobic GFPc was also synthesized for comparison. We further prepared complex colloids containing surfactant-like GFPc linked with a peptide chain. After incubation with protease, the cleavage of peptide gives rise to morphology change and also fluorescence turn-on.
