Functional 3-D Cellulose & Nitrocellulose Paper-Based, Multiplex Diagnostic Platforms Without Coupling Agents, Mackenzie Elizabeth Tageson

Master's Theses

The purpose of this thesis was to demonstrate device functionality of 3-D paper-based, multiplex platforms, µPADs, without the use of coupling agents between layers. Previously, these platforms were fabricated with double-sided tape and cellulose powder to try to augment proper fluid routing, but difficulties with this method occurred. An acrylic housing unit with strategically placed pressure tabs was designed to aid horizontal and vertical fluid routing through the platform, thus eliminating the inconsistencies associated with coupling agents. Channel characterization studies, a COMSOL^TM simulation, and development time studies were performed to aid device design and demonstrate device functionality.
