Managing Real-State on Centrifugal Microfluidic Platforms

Managing Real-State on Centrifugal Microfluidic Platforms

Centrifugal microfluidic platforms, also called compact microfluidic biodisks or compact disks (CD), have been around for almost four decades and have seen a surge in technology advancement in the last decade1. CDs are used in rapid immunoassaying and clinical biochemistry for blood diagnostics. They are used as micro total analysis systems (μTAS), in which several individual assays are embedded and run simultaneously on a single chip. They operate on simple inexpensive motors programmed for hands-free control and do not require external actuators such as magnets or surface treatments. Basically, CDs are great, and this article should end here. Unfortunately, there is a catch: due to unidirectional (radial) centrifugal forces, CDs run out of real estate faster than non-rotating microfluidic devices. (more…)

What’s a Discman and How Is It a Medical Diagnostic Device? (CD Microfluidics)

What’s a Discman and How Is It a Medical Diagnostic Device? (CD Microfluidics)

When I started my pursuit to become a Biomedical Engineer, the last thing I would have ever thought I would end up working in is microfluidics. And why is that? Well, as others in the field have previously discussed, along with friends and family, and even myself; we did not know what microfluidics was. However, this shortly changed as I was fortunate to stumble into the Bio-MEMS laboratory of Dr. Marc Madou at the University of California, Irvine. Dr. Madou specializes and focuses on a specific area of microfluidics known as Compact-Disk or CD microfluidics. One of my fondest memories in the lab was watching a video of Dr. Madou on TedxTalks describing how he was going to turn a Sony Discman into a medical diagnostic device and all I could think to myself was…“What is a Discman?” (more…)
