我们开发了交联凝胶和半柔性生物聚合物（如f -肌动蛋白）的立体纠缠溶液的模型。这种网络在细胞骨架中起着至关重要的结构作用。我们证明了这些网络的神学性质可以由非经典橡胶弹性引起。该模型可以在体外解释这种网络的许多弹性特性，包括存储模量和屈服应变的浓度依赖性。
We develop a model for cross-linked gels and sterically entangled solutions of semiflexible biopolymers such as F-actin. Such networks play a crucial structural role in the cytoskeleton of cells. We show that the theologic properties of these networks can result from nonclassical rubber elasticity. This model can explain a number of elastic properties of such networks in vitro, including the concentration dependence of the storage modulus and yield strain.
