High resolution 3D printed microfluidic devices for particle trapping, on-chip reactions, and detector interfacing
There has been much interest in recent years regarding the potential of 3D printing and its possible chemical and biological applications. Rapid prototyping, low reagent consumption, feedback driven innovation, and ease of fabrication are all attractive reasons this technology has gained traction. There remains a need to develop 3D printing for microfluidic applications with <100 µm features. Recently our group has developed a custom built stereolithography 3D printer and resin formulation capable of printing microchannels as small as 18 µm x 20 µm. We have also formed micro-pillars, ridges and trenches as small 20 µm in diameter (or wide) and devices for capturing particles as small as 25 µm. We are working to interface these devices to a variety of detection methods such as optical and electrochemical. We also are continuing to evaluate these 3D printed microfluidic devices for additional applications such as particle/cell capture and on-chip reactions. All of these applications demonstrate the role 3D printing can play as an essential tool for creating microfluidic devices for chemistry and biology.
