Fall 2011
A capillary-type fluorescent-core microcavity refractive index sensor based on whispering gallery mode (WGM) resonances is presented. The device consists of a glass microcapillary with a thin layer of fluorescent silicon quantum dots (QDs) coated on the channel surface. The high index of the QD...

2015 marks the 50th anniversary of Moore's law, which has described the exponential progress in semiconductor patterning technologies, enabling creation of smaller circuitry features at greater densities. These continued hardware developments, economically mass manufactured, have made possible...

Nanomechanical resonators are explored as mass sensors and molecular sensors due to their high sensitivity and real time label-free detection ability, respectively. One downside of mechanical molecular sensing is the lack of chemical information carried in the signal. For this reason, a...

On a perfect hydrogen-terminated Si(100)-2x1 surface, each surface silicon atom is capped with exactly one atom of hydrogen. When one of the capping hydrogen atoms is removed, the now unsatisfied orbital of the underlying silicon atom is exposed at that site. This site is better known as a...

Electron Beam Lithography (EBL) is a powerful tool for structuring materials at the deep nanoscale. Modeling and simulation of electron-beam interactions at this length scale is vital to understanding and optimizing nanofabrication using EBL. The low to high voltage (5 keV – 100 keV) regimes of...

We present a platform for research into nanomaterial-enhanced gas sensing using magnetomotive MEMS resonators. A microfabrication process fl ow is developed and carried out to create metallized silicon MEMS resonators. In tandem, a test system based around a balanced electronic bridge is...

Views in Hudson’s Bay (1825) and Peter Rindisbacher: Constructions of Indigenous and non-Indigenous Culture in the Red River Settlement
DownloadSpring 2017
Within the Views in Hudson’s Bay (1825) print series are six hand-tinted lithographs depicting indigenous and non-indigenous culture in the Red River Settlement. The images engage with visual language from eighteenth- and nineteenth-century print series and travel books that construct North...

Hide and Seek is a children’s game. It can also be thought of more broadly as the act of concealment and of searching. The works in this exhibition ask viewers to consider the things from our past that we consciously and subconsciously hide as well as the objects and spaces in which we seek...

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...

Molecular self-assembly is the basis of structure in Nature. While of far less complexity than a natural system, the same physical rules apply to simple synthetic designed systems that spontaneously form self-assembled structures and patterns. The self-assembly of block copolymers (BCPs) is an...
