On combining P11-13 (Q,-6) and P11-14 (Q,+4), the composite system now has an average net charge of -2 per peptide, within the range where hydrogels are formed in single component peptide systems, c.f. P11-4 (Q,-2). Indeed, this combination of highly charged peptides led to the formation of a self-supporting hydrogel as shown in Figure . The G' and G" of the P11-13/14 (Q,-2) hydrogel was considerably lower than that of P11-4 (Q,-2) by three orders of magnitude. The G' of the composite P11-13/P11-14 (Q,-2) system was ~32 Pa and G" ~12 Pa, compared to P11-4 (Q,-2) where G' and G" were 12 and 4 kPa respectively. The phase angle of both systems were not dissimilar, P11-13/14 (Q,-2) ~18° while P11-4 (Q,-2) is ~15°. However, while the moduli of the composite system were greatly reduced, likely due to the high charge density in the hybrid hydrogel, a self-supporting hydrogel that could resist flow under gravity formed upon combining these non-gelling individual peptides.
