a FRAP images and relative fluorescence intensities of GY23 coacervates after 15 minutes incubation. Data presented as mean ± SD, t0.5 indicate the time required for 50% recovery to maximum intensity, which is significantly lower than freshly made GY23 coacervates in Fig. 3e, two-sided Student’s t test, *P < 0.001. b Storage modulus (G’) and loss modulus (G”) of GY23 coacervates incubated at room temperature for various time periods. c FTIR spectra of GY23 coacervates after incubation at room temperature for various time periods. d, e Curve fitting of the amide I peak of GY23 coacervates incubated at room temperature for 0 minutes (a) and 30 minutes (b), showing the shift towards b-sheet structures over time. All peptides form coacervates at the test conditions.
