制造了铁蛋白基纳米纤维水凝胶，其证明了铁蛋白和合成聚合物基质之间的协同作用。混合水凝胶显示出增强的机械性能和反复膨胀和收缩，而不显示严重的蠕变过程中的pH值切换。掺入水凝胶纳米纤维中的铁蛋白纳米颗粒通过充当纳米级聚合物中的弹性纳米弹簧来改善水凝胶致动器的致动稳定性。
Ferritin-based nanofibrous hydrogels that demonstrate synergy between the ferritin protein and the synthetic polymer matrix are fabricated. The hybrid hydrogels showed enhanced mechanical properties and repeated expansion and contraction without showing severe creep during pH switching. The ferritin nanoparticles incorporated into the hydrogel nanofibers improved the actuation stability of a hydrogel actuator by acting as elastic nanosprings in a nanoscale polymer.
