摘要

我们考虑一个突出的例子，一个活跃的生物流体，即真正的黏菌绒泡菌多头的细胞质。我们将细胞骨架建模为一种固体基质，与作为间隙流体的细胞溶胶一起构成一种活性的孔隙弹性材料，并重现了大量实验观察到的机械化学波形，如螺旋、湍流、靶波。

Dynamics of Physarum Microdroplets - an Example for Mechanochemical Pattern Formation in Active Biological Matter

We consider one prominent example for an active biological fluid, namely the cytoplasm of the true slime mold Physarum polycephalum. We model the cytoskeleton as a solid matrix that together with the cytosol as interstitial fluid constitutes an active poroelastic material and reproduce a large variety of experimentally observed mechanochemical wave forms, e. g. spirals, turbulence, target waves.
