## What is Pore2Chip?

-
Pore2Chip is a Python module designed to streamline the process of analyzing X-ray computed tomography (XCT) images of soil and creating 2D micromodel designs based on that analysis. It leverages the power of open-source libraries like OpenPNM, PoreSpy, and drawsvg to extract key information about the soil's porous structure and translate it into a blueprint for microfluidic simulations or physical "lab-on-a-chip" devices developed using additive manufacturing.
