Temperature-triggered macroscale self-assembly of FAMEs. a-i, Temperature-programmed turbidimetry assays and images (c, f, i) obtained after heating above Tc and cooling below Tt for B1-ELP (a), M-B1-ELP (b, c), B2-ELP (d), M-B2-ELP (e, f), B3-ELP (g), and M-B3-ELP (h, i). Each turbidimetry assay was carried out at three concentrations: 100 μM (solid lines), 50 μM (dotted lines), 25 μM (dashed lines). The arrows denote the onset of LCST behavior (Tt) (a,b) and the onset of hysteretic behavior and morphogenesis of M-B2-ELP (e) and M-B3-ELP (h) into macroscopic structures above the critical temperature (Tc). The images in c, f, and i demonstrate that the self-assembled structures formed by M-B2-ELP and M-B3-ELP on heating are stable upon cooling (f,i), whereas that formed by M-B1-ELP resolubilizes (c).
