The focus of this thesis is on electro-osmotically pumped flow of viscoelastic fluids through microchannels. Fluid transport in microscaled structures is typically laminar due to the low Reynolds numbers involved. However, it is known that viscoelastic polymeric liquids can display striking...
Genetic analysis is not widely used for disease diagnostics as it is costly and very labour/infrastructure intensive. We believe that by employing both microelectronic and microfabrication technologies, we are able to integrate multiple functionalities into a single, manufacturable, inexpensive...
Lab-on-chip systems will be a major component in the future of health care. These technologies enable point-of-care testing by miniaturizing and improving the efficiency of many diagnostic techniques. Possible applications include the detection of various pathogens using genetic amplification...
The aim of this study is to develop a technique capable of performing three-dimensional particle tracking by using images from a plenoptic (or light field) camera. Use of a plenoptic camera enables the collection of three-dimensional positional data within a volume, which would normally require...
This work describes the development of a planar moving flexible valve in polydimethylsiloxane (PDMS) with integrated optics components on a microfluidic device. Applying a positive pressure to a side channel, the fluid inside deforms the flexible PDMS which then redirects the flow in a main...
Clinical point-of-care (POC) diagnosis remains an open and challenging field of research worldwide in which the study of the mechanism and dynamics of protein molecule separation using electrophoresis is of considerable interest. The quality of a protein separation is strongly dependent on the...
The BIOMEMS interdisciplinary research group has been working to produce single chip Lab-on-Chip systems for genetic diagnostic applications. By bringing a genetic diagnostic platform down to the size of a single Lab-on-Chip integrated circuit we can enable fast testing at the point of care. One...
One of the central puzzles concerning the interaction of low Reynolds number (Re<<1) fluid transport with bacterial biomass is the formation of filamentous structures called bacterial streamer. Bacterial streamers can be tethered at one or both ends to solid surfaces, while the rest of the...
This thesis reports the separation behavior of SDS-protein complexes in colloidal self-assembled (CSA) nanoparticle beds, and the processes of stabilization of CSA beds for high voltage separation. First, the variation of electrophoretic mobility with molecular weight (6.5-66 kDa) of SDS-protein...
The infrastructure necessary to support diagnostic and pathogen-detection processes does not exist in some regions of the world that need it most. Access to fast, inexpensive and portable diagnostic infrastructure could be a solution to this problem. Next generation lab-on-chip (LOC) systems that...
