Lab on a Slab: Microfluidics Activity

Microfluidics is a technique for manipulating liquid samples. With one drop of liquid sample, small devices and channels can be used with nanoparticles for sensitive detection of chemicals. In this lab, students will create a fluidic device with agar gel and use it to test and diagnose three patient samples for pH, starch, and peroxide content. This lab is designed to help students understand fluid flow, capillary action, surface tension, and chemical tests used in microfluidic devices/sensors.
