Fall 2015
The expansion of the fluorescent protein (FP) colour palette through discovery of more species possessing FPs and by subjecting them to intensive protein engineering efforts has greatly aided the effectiveness of FP-based biosensor designs. Currently, the main FP-based methods for detecting...

Spring 2010
The procedure for milling micrometre scale cantilevers of lutetium iron garnet using a focused ion beam microscope was developed. The infrastructure to study these cantilevers using rotational hysteresis loops and ferromagnetic resonance experiments was set up. The cantilevers were shown to...

Spring 2013
An alternative method of manipulating fragile MEMS devices during fabrication has been developed. A specialized manual or robotic end effector utilizing a gecko inspired adhesive can replace the slow and costly manual tweezers used by the MEMS foundry Micralyne Inc. Improving the adhesive...

Integration of Nanomechanical Resonators in Microfluidic Systems for Specific Protein Detection
DownloadFall 2009
Nanomechanical resonators offer a pathway towards highly sensitive and label-free detection of biomolecules by transducing the mass of bound analytes into resonant frequency shifts. Zeptogram level and even single cell detections have been successfully achieved by others. However, these...

Metallic thin films for NEMS/MEMS: from fundamental behaviour to microstructural design and fabrication
DownloadFall 2011
The main focus of this thesis is the study of thin metal films in microelectromechanical/nanoelectromechanical systems (MEMS/NEMS), ranging from application to fundamental behaviour. The use of metallic structural components is desirable since they are electrically conductive, optically reflective...

Fall 2020
This thesis describes the theory, fabrication, and characterization of on-chip, integrated Fabry-Perot microcavities embedded with thin silicon nitride membranes. The approach combines a previously developed process for fabricating self-assembled Si / SiO2 / Ta2O5 curved mirror cavities, with a...
