Nanofluidics studies fluid properties in channels ~1,000x thinner than a strand of hair. Nanofluidics research is popular in sensing, medicine, water treatment, and biology because operating at this scale unlocks new capabilities in engineering and detection. For example, micro and nanofluidic principles could help enable a rapid COVID-19 analysis tool. Such a platform might include fluidic pumps for moving the sample, fluidic valves and filters for separating components, and fluidic mixers for introducing reagents. These are some concepts I have developed during my Ph.D.
