Theoretical estimates reveal the presence of strong thermal hydrodynamic fluctuations in the cytoplasm of living cells. It is suggested here that these intensive fluctuations may be utilized by biological vesicles inside the cells to produce their directed drift to the targets. A possible mechanism of partial rectification of thermal fluctuations is based on the effect of active navigation: i.e. on the controlled response of vesicles to velocity fluctuations.
理论估计表明,活细胞的细胞质中存在强烈的热流体动力学涨落。本文提出,细胞内的生物小泡可能利用这些强烈涨落使其向目标产生定向漂移。热涨落的部分整流的一种可能机制基于主动导航效应:即基于小泡对速度涨落的可控响应。
