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...

Large-Scale Multi-Frequency Capacitive Micromachined Ultrasonic Transducer (CMUT) Arrays for Ultrasound Medical Imaging and Therapeutic Applications
DownloadSpring 2020
Ultrasonic transducers capable of operating over multiple frequency bands could have several interesting medical applications including multi-resolution multi-depth imaging for point-of-care ultrasound, imaging-therapy, super-harmonic contrast agent imaging, super-resolution imaging, image-guided...

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...

Nanophotonic detection of nanomechanical structures for use toward mass sensing applications
DownloadSpring 2014
Nanomechanical beam resonators show much promise for use in integrated on-chip mass sensing systems. This follows from their own very small masses and also their ability to store the mechanical energy of their oscillations to produce strong measurable mechanical response signals. To achieve...
