Extended Data Fig. 6: Dye encapsulation.

a-b Tryptophan fluorescence spectra of WKY (20 mM in 100 mM PB pH 7.5) in the absence and presence of dye at increasing concentrations (10 µM, 100 µM, 500 µM): (a) Alexa 488, (b) Crystal Violet. c. Confocal live imaging of WKY peptide particles incorporating crystal violet shows substantial enrichment of the dye in peptide droplets, and the dried particles post-encapsulation were shown in d. Scale bar = 50 µm. e. Fluorescence intensity analysis of the pre-load solution, the peptide droplet, and the post-load solution at the frontier of emulsification. A total of 20 regions of interest of each group from 6 time-lapse frames were quantified, and the average intensity of pre-load solution was set as 1 arbitrarily. Error bar represents s.d.
