Hello everyone! I am curious to learn how laboratories handle in-house chip manufacturing using soft lithography for microfluidics research.
In the lab where I worked, only the mask for lithography was made by an external company, whereas the mold and chip fabrication were carried out by us.
The process of making PDMS chips required around 30 min–1 h of manual work between prepolymer casting, punching/cutting, and plasma bonding. However, the total time required to make them was around 4...
