ENBIOS-1D Lab is a tool to illustrate and to study simple Electrolyte, Electrolyte/Insulator and /Electrolyte/Insulator/Semiconductor systems in one dimension. It is meant for use as a teaching tool in support of undergraduate or graduate courses on the basic physics of transduction in ion and particle sensors, and to assist early stage researchers getting familiar with some basic concepts in the field. At the present stage, ENBIOS-1D Lab supports simulation and visualization of impedance/admittance spectra as well as DC and AC potential/ion distributions in simple one-dimensional Electrolyte (E), Electrolyte/Insulator (EI) and Electrolyte/Insulator/Semiconductor (EIS) systems. A broader set of case studies will become available with future releases of the tool, possibly including Ion Sensitive Field Effect Transistor (ISFET) and Nanoelectrode array devices. The physical systems are modelled with the Poisson/Boltzmann (DC) and Poisson/Nernst/Planck - Poisson/Drift/Diffusion (AC small signal) equations. Dedicated models are implemented for the build up of site-binding charge at Electrolyte/Insulator interfaces and for the frequency and salinity dependence of the electrolyte electrical permittivity. ENBIOS-1D Lab is powered by ENBIOS, (Electronic Nano-BIOsensor Simulator), a general purpose three-dimensional Control Volume Finite Element Method (CVFEM) simulator developed in-house at the University of Udine - Italy. ENBIOS simulates in three dimensions (3D) the DC and AC small signal impedance response to ions and micro/nanoparticles of three-dimensional devices made of semiconductor, insulator and electrolyte materials.
