Abstract: To implement analytical chemistry processes in digital microfluidic systems, consideration is required for three concepts: actuation, sensing, and stimulation. The scalability of the architectures that enable these components is critical to creating innovative and accessible analytical equipment. By using microelectromechanical systems these architectures can be actualized. Actuation through digital microfluidics allows for highly specific quantification of analytical processes. The scalability of actuation architectures has been addressed thoroughly through previous works. However, the scalability of both sensing and stimulation requires further development and this thesis addresses this issue. This thesis provides a fibre-optic sensing architecture for scalable sensing in digital microfluidic devices. This architecture is explored theoretically and experimentally. This thesis also provides a method for scalable stimulation for annealing in polymerase chain reaction, using infrared excitation. The optical stimulation is shown theoretically and experimentally.
