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...
Electro-transmittance of molecular junctions was characterized electrically and studied optically at 410nm and 532nm. Between 1kHz and 100kHz there was no qualitative difference between the control samples and the molecular junction samples, however there were difficulties with reproducibility of...
This dissertation investigates the size based separation of DNA molecules in nanoparticle arrays under asymmetric pulsed electrophoresis. Crystalline arrays of nanoparticles within microfluidic channels are fabricated using colloidal self-assembly, yielding structures with pore sizes ranging from...
Design and Microfabrication of Robust and Highly Integrated Thermal Lab-On-A-Chip Polymeric Systems for Genetic DiagnosisDownload
The lab-on-chip (LOC) technology could transform and greatly enhance the health care system by making genetic diagnosis tests fast, accurate and readily accessible. However, most LOC systems are not prepared to resist variations of their external environment, as they depend upon many...
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...
Development of Microfluidic Chips and a Customised Flow Control System for use in a Label-Free CytometerDownload
Conventional cytometry uses fluorescently labelled cells that are laborious and costly to prepare. Using a label-free technique, individual cells can be differentiated by light scattering patterns, a result of different physical attributes. This thesis describes the development of a microfluidic...
The development of rapid detection techniques to be applied at the point of use, has been gaining significant attention in the recent years. Rapid techniques are important and preferable methods in healthcare and environment sector due to the advantages they offer such as low-cost and reduced...
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...
We demonstrate the functionalization of a highly ordered porous molecular sieving matrix created by colloidal self-assembly (CSA) of 2 micrometer diameter silica particles in microfluidic chips, for highly efficient immuno-capture of viruses. By tuning the particle size, with appropriate surface...
Towards minimizing the cost of Micro Total Analysis Systems(µTAS) or Lab on a chip (LoC) systems, it is important to minimize manufacturing and assembly cost and time, and lower material costs. While the choice of material does govern material costs and the manufacturing process required and...
