Think back to the last time you got a blood test. Maybe you had your cholesterol checked or got screened for infections, heart disease, stroke risk, thyroid troubles, or osteoporosis. Easy, right? A nurse simply drew your blood and shipped the vials to a lab. But behind the scenes, the process gets more complex. Today’s laboratory technologies require rooms full of temperature-controlled chemicals, analytical machines worth hundreds of thousands of dollars, and trained technicians to run them. That’s why it probably took days, maybe even a week or two, to get your results. And depending on the tests, a panel of them could easily have set you back several hundred dollars.

If you want to enhance your modeling and design processes for microfluidic organ-on-a-chip devices, tune into this webinar.

You will learn methods for simulating the performance and behavior of microfluidic organ-on-a-chip devices and microphysiological systems in COMSOL Multiphysics. Additionally, you will see how to couple multiple physical effects in your model, including chemical transport, particle tracing, and fluid–structure interaction. You will also learn how to distill simulation output to find key design parameters and obtain a high-level description of system performance and behavior.
