Microfluidic technology involves moving tiny amounts of liquids to perform various functions: ink in an inkjet printer, solder on an electronics board, bodily fluids within a medical device to perform chemical analyses. The use of this technology isn’t exactly new, but its popularity is rapidly rising.

Multilayered microfluidic devices — the majority of microfluidic devices — typically have channels built into the device through which the specific amount of fluid flows at a particular speed and path. Construction is accomplished by either adding channels between layers or subtracting material from a solid sheet to form channels. These individual layers eventually need to come together in one usable package or device.

There’s often a fine line between health and illness. Microfluidic devices detect important samples of fluids that provide crucial information to patients and their caregivers.

However, microfluidics requires the right materials to ensure accuracy as these critical tools are designed, manufactured, and assembled. Usually small with intricate channels and circuits, microfluidic devices require the exact right material properties.

Towering redwoods. Majestic mountain peaks. Complex cloud formations. As we take moments to appreciate nature’s large displays of beauty, many of us rarely recognize small engineering feats that allow us to live comfortable lives.

The study of microfluidics contributes significantly to many fields that affect our daily lives. For instance, microfluidic devices carry tiny amounts of fluid that give caregivers and patients accurate test results, from monitoring blood glucose to detecting pathogens.

If you don’t already know about microfluidics, this article is an excellent look at the power of such tiny wonders. We’ll explore the basics of microfluidics, what microfluidic devices are used for, and how to make a microfluidic chip. Ready?

Microfluidics’ ability to perform chemical analyses of small volumes of fluids have reduced hospital visits and overall healthcare expenditures. And, their use is rising rapidly.

Although small in size, microfluidic devices carry an enormous burden. Patients and caregivers rely on them for accurate test results and crucial information at the point-of-care. They screen for cancer, monitor blood glucose, detect pathogens. As they transport and protect samples of blood or other fluids, consistent and reliable performance is imperative.
