Pixel Imaging Method, Transport Phenomenon in Sizes From Nano, Micro, and Milli Scale Pore Membrane

Abstract

In this article, we develop NanoSoft SoftLab GUI circuit model and oscillator model to study the current–time and current–voltage characteristics inside the nanopore membrane. We study the ion transport for silicon nitride sputtered with silicon dioxide (Si₃N₄–SiO₂) nanopore membrane, graphene, and molybdenum disulfide (MoS₂) nanopore membrane. Further, we apply our two models to understand the ion transport in two polydimethylsiloxane (PDMS) micropore reservoirs connected in series with no nanopore membrane. Furthermore, we perform circuit simulations on silicon nitride sputtered with silicon dioxide with pore radius varying from nanometer to millimeter to obtain current from pA to μA. Here we develop NanoSoft visualization software to match the silicon nitride nanopore membrane. We develop open-loop controller model to relate the ionic current in the nanopore to the nanofluidic calculator output. Our work can find applications for energy-efficient nanofluidic processors and computers to build towards the recent nanofluidic memristive synapse-like memory dynamics literature.
