In this research internship, I learned about and explored the applications of microfluidics, which culminated in independent experimentation. My co-intern and I began by studying the mechanics of microfluidic systems, both to decrease fouling as well as purify water. Once we had a better understanding of the concept, we decided on the question we wanted to answer through microfluidics. We decided to create experiments wherein we removed mehtlyene blue, a salt used as a medication and dye, as this is a good substitute for volatile organic compounds in water. From there, we conducted several experiments with different geometries in an attempt to find the most efficient structure.
