Introduction to Multiphase Microfluidics

Microfluidic systems have revolutionized biotechnology, chemical synthesis, and medical diagnostics by manipulating tiny amounts of fluids. Understanding how multiple phases—such as droplets, bubbles, and immiscible liquids—interact at the microscale is essential for designing modern lab-on-a-chip devices. In this text-based course, you will build a solid foundation in the governing physics of multiphase microfluidics. You will transition from learning basic fluid mechanics to understanding how to generate, manipulate, and analyze microdroplets and liquid-liquid interfaces. What you'll learn: - Understand the fundamental physics of microscale flows, including surface tension, capillary forces, and dimensionless numbers. - Analyze flow regimes and patterns of multiphase mixtures inside microchannels. - Explore droplet-based microfluidics, including generation methods like flow-focusing and T-junctions. - Examine modern applications such as digital microfluidics and organ-on-a-chip platforms. - Study the principles of microfabrication and materials commonly used in microfluidic device construction. The course begins with core definitions and the fundamental physics governing microscale fluid dynamics. You will then progress through the mechanics of multiphase interfaces, droplet generation techniques, and real-world engineering applications. This course is designed for beginners in engineering, physics, chemistry, or biotechnology who want to understand microfluidics without needing prior experience in the field.
