Continued interest in the development of miniaturized and portable analytical platforms necessitates the exploration of sensitive methods for the detection of trace analytes. Nanomaterials, on account of their unique physical and chemical properties, are not only able to overcome many limitations of traditional detection reagents but also enable the exploration...
This report details preliminary studies towards the development of a microfluidic
sensor that exploits ferromagnetic resonance, excited in magnetic bead labels, for signal
transduction. The device consists of a microwave circuit in which a slotline and a coplanar
waveguide are integrated with a biochemically activated sensor area. The magnetic beads...

Gene synthesis is an important tool in molecular biology. However, the current
bench-top method of gene synthesis is a costly, time-intensive and reagent-consuming
process. Lab-on-chip technology has many benefits over current bench top methods.
Microchips consume smaller reagent volumes, are reusable and less expensive to make.
This thesis explores the...
The objective of this thesis is to introduce and demonstrate a novel magnetic bead detector based on inductive detection at the ferromagnetic resonance (FMR) frequency for use in bio-sensing applications. Detection ability is demonstrated through theoretical arguments, numerical computer simulations, and experimental characterization of micro-fabricated detectors.
The detector is composed...
A system of Photoactuated Droplet Microfluidics (PDM), in which a droplet of
fluid is moved by way of the manipulation of the wettability of a spiropyran
functionalized surface via irradiation with ultraviolet and visible light, was proposed. The
photochromic behaviors of several species of spiropyran were studied and a procedure...
Microscale hydropower, facilities that produce between 1 kW and 1 MW of power,
has the potential to revolutionize modern power production. Unlike conventional large scale
operations, these water supplies can be utilized with little impact on the environment.
Hydropower per unit production can be very affordable compared to other renewable...
The recency of the Food and Drug Administration menu-labeling regulations and the lack of research available on restaurateur response initiated this study. Advocates claim the new regulations will protect consumers and foster the selection of nutritious choices, however, critics believe the regulations will result in restaurateurs removing all nutrition information...
