Gels and turbidity changes during gelation. (a) Photographs of gels formed from gelators 1–6. The scale bar represents 1 cm. (b) Change in turbidity during gelation at 600 nm for gels 1–6, showing different kinetics patterns. Logarithmic axis is used, due to time–scale similarities in the rate of assembly for some gels. All gels at a concentration of 5 mg mL−1 and a ratio of DMSO to water of 2:8.
