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...

Spring 2015
Fluorescent proteins (FP) and FP-based biosensors have become essential tools for cell biology and neuroscience research. This thesis describes efforts to engineer new FPs with red emission and novel genetically encoded biosensors based on red FPs. Directed evolution and semi-rational design are...

Development of a Multisectorial Electroactive Nanowell Platform for Selective Single-Cell Sorting and Quantification
DownloadSpring 2022
The rapid isolation of specific rare target cells is of rising importance in current targeted patient treatment plans. Common cell sorting approaches such as stream-based dielectrophoresis (DEP) based cell sorters are limited by their spatial dimensions as only a number of cell types...

An examination of linking and blocking procedures for use in deflection cantilever array-based protein detection
DownloadFall 2011
In this project common linking and blocking procedures were examined for use in multiplexed deflection cantilever array-based detection of proteins. A human interferon gamma (INF-γ) enzyme-linked immunosorbent assay (ELISA) kit was used to evaluate the effectiveness of the linking and blocking...

Fall 2009
Resonant microcantilevers are promising transducers for bacteria detection because of their high sensitivities. Surface stress and mass from adsorbates affect the resonant frequency. We developed a novel method for decoupling the frequency contributions of a change in mass and surface stress on a...

Spring 2013
The sources of inducing field gradients and their implications are investigated inside the microfabricated post arrays. A parametric study is conducted to understand how the posts arrangements, distance, and size change the field and field gradients. The results provide criteria where the...

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...

Development of an optical biosensor based on Mach-Zehnder Interferometry for detection of Listeria monocytogenes
DownloadFall 2013
Label-free optical biosensors are widely used for the detection of pathogens due to their low-cost, real-time detection and high sensitivity. A Mach-Zehnder Interferometer (MZI) based biosensor has been developed for the detection of gram-positive bacteria, Listeria monocytogenes. An extensive...
