Advancing Microfluidics Research Using High-Speed Cameras

Source: Vision Research, Inc.

High-speed cameras can play an important role in microfluidics research. Vision Research, as providers of Phantom high-speed cameras, has a lot of experience in this area, and our resident expert, Nick Long, Vision Research OEM Manager, has extensive knowledge and application experience using high-speed cameras in microfluidics.  Some of this experience and Nick’s knowledge was documented, collaborating with Photonics Online to create a white paper covering the challenges and importance of using high-speed cameras in this evolving field.   Why Photonics Online? It is an Internet leader in delivering cutting-edge technical information information concerning laser, optics, optoelectronics, fiber optics, and imaging industries.  Their free memberships give access to the latest information in a wide variety of topics like; camera/display components, light sensors, LED, fiber optics, and much more.

 While microfluidics research is a relatively new field, it is a very rapidly expanding field of research. Microfluidics involves manipulating and studying small amounts of liquid (often in channels or living vessels), which are typically only ten microns wide. With these fluids moving very rapidly, too fast to analyze with standard cameras, high-speed cameras step in to save the day! Many microfluidic applications typically require speeds of 3,000 to 25,000 frames per second (fps), and some could even benefit from speeds exceeding 200,000 fps. Researchers do not only want to simply capture these images of fluid dynamics; they want to also be able to extract quantitative data, which is where choosing the right camera becomes very important.

The new white paper covers common areas to consider when using high-speed cameras, a common imaging technique used in microfluidics, and discussions on particle imagining velocimetry (PIV) and particle tracking velocimetry (PTV), examples.  It also references a published droplet fluidics experiment using a Phantom high-speed camera, and even has imbedded videos from a demonstration using Shadowscopy. Take a look, and if you have more questions on high-speed imaging in microfluidics, don’t hesitate to ask. With all of these great breakthroughs in technology and the combination of high-speed cameras and computer software, scientists will keep furthering this field of research to help develop new and very useful technologies.  It’s an exciting field, and Vision Research is proud to be a part of it!
