论文摘要
由蛋白液滴观察到细胞内相分离和细胞膜润湿的动机，我们研究了涉及粒子产生的晶格气模型的蒙特卡洛模拟的非平衡表面润湿。我们发现，即使应以平衡状态进行完全润湿，由于散装液滴的形成，颗粒的快速产生可能会阻碍表面润湿。进行分子动力学模拟，我们表明，当疾病密度足够高时，这种情况也存在于胶体颗粒系统中。结果表明，通过改变组成速度合成的速度，具有细胞内控制机制。
Motivated by the observations of intracellular phase separations and the wetting of cell membranes by protein droplets, we study the nonequilibrium surface wetting by Monte Carlo simulations of a lattice gas model involving particle creation. We find that, even when complete wetting should occur in equilibrium, the fast creation of particles can hinder the surface wetting for a long time due to the bulk droplet formation. Performing molecular dynamics simulations, we show that this situation also holds in colloidal particle systems when the disorder density is sufficiently high. The results suggest an intracellular control mechanism of surface wetting by changing the speed of component synthesis.
