A simple kinetic model of a two-component deformable and reactive bilayer is presented. The two differently shaped components are interconverted by a nonequilibrium reaction, and a phenomenological coupling between local composition and curvature is proposed. When the two components are not miscible, linear stability analysis predicts, and numerical simulations show, the formation of stationary nonequilibrium composition/curvature patterns whose typical size is determined by the reactive process. For miscible components, a linearization of the dynamic equations is performed in order to evaluate the correlation function for shape fluctuations from which the behavior of these systems in micropipet aspiration experiments can be predicted.
本文提出了一种双组分可变形且有反应活性的双层膜的简单动力学模型。两种形状不同的组分通过非平衡反应相互转化，并提出了局部组成与曲率之间的唯象耦合。当两种组分不可混溶时，线性稳定性分析预测并经数值模拟表明，会形成典型尺寸由反应过程决定的稳态非平衡组成/曲率模式。对于可混溶的组分，对动力学方程进行线性化处理，以评估形状涨落的关联函数，据此可预测这些系统在微吸管抽吸实验中的行为。
