本文提出了一种高精度的纳米粒子计数和尺寸的方法，使用微谐振器波导系统，其中包含一个流通的纳米孔。基于耦合模理论进行了理论分析，表明当纳米颗粒通过纳米孔时，可以检测到时间脉冲信号，并且峰值幅度线性地依赖于纳米颗粒体积。据估计，可以检测到尺寸小于10 nm的纳米颗粒。
This paper proposes a high precision method for nanoparticle counting and sizing using a microring resonator-waveguide system that contains a flow-through nanopore. Theoretical analysis is carried out based on the coupled-mode theory, showing that when the nanoparticle passes the nanopore a temporal pulse signal can be detected and that the peak amplitude depends linearly on the nanoparticle volume. It is estimated that a nanoparticle of sub-10 nm in size may be detectable.
