The precise engineering required to build microfluidic test patterns
In short: Watch a technical walkthrough of the fabrication process for microfluidic devices. This tutorial covers the essential steps of curing, cleaning, and bonding PDMS to create functional micro-scale channels.
This tutorial from MIT's Nanomaker course details the transition from raw materials to a functional microfluidic device. The process involves curing Polydimethylsiloxane (PDMS), opening specific inlet and outlet ports, and performing a rigorous cleaning of the material.
The final stages of fabrication involve bonding the PDMS to a glass substrate and applying a corona treatment. These steps are critical for ensuring the device can handle fluids at the microscale without leaks or structural failure.
