Physical parameters of macromolecules are determined by measuring electrical current I over time for translocation events as the macromolecules in solution move between two liquid compartments that are separated by and fluidically coupled through a synthetic nanopore. Values of charge, volume, shape, rotational diffusion coefficient, and dipole moment are derived from the measurements.
当溶液中的大分子在被合成纳米孔分隔和流体耦合的两个液室之间移动时,通过测量移位事件随时间变化的电流 I 来确定大分子的物理参数。电荷、体积、形状、旋转扩散系数和偶极矩的值都是通过测量得出的。
