Cantilever sensors have attracted considerable attention over the last decade because of their potential as a highly sensitive sensor platform for high throughput and multiplexed detection of proteins and nucleic acids. A micromachined cantilever platform integrates nanoscale science and microfabrication technology for the label-free detection of biological(More)
iii ACKNOWLEDGEMENTS I would first like to thank the good Lord for supplying His grace to finish this work. The Lord has provided people of excellence to help complete the present thesis. First, I would like to thank my lead research advisor, Dr. Comas Haynes, for loving me as his "academic son." Without Dr. Haynes' love, guidance, and support, this work(More)
This paper presents work on the development of a microfluidic device using super-paramagnetic beads for sampling and mixing. The beads are manipulated via an external rotating permanent magnet in a microfluidic channel. Efficient mixing is achieved in a short distance with this method. Modeling shows the variables which influence the mixing are flow rate,(More)
In this work we present a high performance micro gas chromatograph column with a novel two dimensional axial heating technique for faster and more precise temperature programming, resulting in an improved separation performance. Three different axial resistive heater designs were simulated theoretically on a 3.0 m × 300 μm × 50 μm column for the highest(More)
