Electrokinetics for the Separation of Particles and Potential Water Purification
I conducted research to determine new methods for purifying water. Billions of people worldwide lack access to clean water and proper sanitation. With the human population growing rapidly, there is a need to improve water-purification technology to meet the demand for water. For my internship, I explored how electrokinetically induced diffusiophoresis would affect the transport of electrolytes out of dead-end pores. I created microfluidic channels using soft lithography techniques. In addition, I used a microscope with live imaging and a fluorescent mode to capture images that I later analyzed using ImageJ image-processing software. Through this internship, I gained experience in a myriad of laboratory techniques such as plasma treatment methods and microscopy. I also furthered my data-analysis skills and developed experience using ImageJ. This internship gave me insight into the role of multiple electrolytes in particle movement in fluids and it made me want to pursue a more research-based career path.
