Microfluidics

This 6-page lab guide, created by the Nanotechnology Applications and Career Knowledge (NACK) Center at Pennsylvania State University, features an activity that introduces students to microfluidics, or "different applications of fluid transport through channels and networks in the micron regime." Over the course of the two-day lab, students will "perform negative lithography on a silicon substrate to create a master mold," and "determine the channel dimensions with the profilometer." Upon completion of the exercise, students should be able to "Compare the channel dimension of the mask to the channel dimensions achieved after photolithography" and "Explain how photoresists are used." The lab guide includes background information, step-by-step instructions for the experiment, and post-lab student questions.
