This system operates under laminar flow conditions, allowing for negligible inertial effects and enabling differential transport of desired particles into an extraction stream through diffusion. Coupling this extraction system with microfabricated diffusion-based mixing devices or sensing means facilitates the processing and analysis of picoliter quantities of fluid on devices as small as silicon wafers.

Another innovative invention by Hixson is a microfabricated diffusion-based chemical sensor. This channel-cell system is engineered for detecting and measuring the presence of analyte particles within a sample stream. It features a laminar flow channel with two inlets that introduce an indicator stream and a sample stream. The design allows for laminar flow, enabling analyte particles to diffuse into the indicator stream while effectively excluding larger particles, thus forming a defined detection area. The outlet then conducts the streams into a single mixed output for further analysis.
