High-Throughput, Portable Microfluidic Aptamer Assay, Atticus Mccoy, Matthew Curtin

Bioengineering Senior Theses

Aptamer-based assays are a powerful platform for sensing a wide variety of biochemical targets, including drugs, disease biomarker, and biomolecules. However, aptamer assays often lack rapid identification and high-throughput screening. Performing an aptamer-based assay on a microfluidic device is a promising solution to increase throughput, portability, and sensitivity. In this paper, we present a microfluidic device capable of running aptamer-based assays. Our device utilizes normally-closed valves and a central micropump to move fluids throughout the chip. One chip could theoretically be scaled up to run multiple assays, and multiple of these microfluidic devices could be run in parallel to increase …

Noninvasive Screening Of A Fecal Biomarker For Human Necrotizing Enterocolitis (Nec), Daniela Campa, Kyle Sullivan

Bioengineering Senior Theses

Necrotizing enterocolitis (NEC) is a disease that predominantly affects preterm infants. Of the 10% of preterm neonates that develop NEC, about one in four cases results in death. The pathophysiology presents as inflammation of intestinal epithelial cell lining and subsequent tissue death, sometimes resulting in intestinal perforations. The underlying mechanisms have yet to be comprehensively identified. Diagnosis--the rate limiting step in reducing critical disease-onset-to-treatment time--is based on relatively nonspecific signs, impeding early and accurate diagnosis. This project, a collaborative effort between Santa Clara and Stanford Universities, aims to improve current diagnostic methods by identifying the first verifiable and useful fecal …

A Historical Sedimentary Record Of Mercury In A Shallow Eutrophic Lake: Impacts Of Human Activities And Climate Change, Hanxiao Zhang, Shouliang Huo, Kevin M. Yeager, Beidou Xi, Jingtian Zhang, Fengchang Wu

Earth and Environmental Sciences Faculty Publications

Mercury and its derivatives are hazardous environmental pollutants and could affect the aquatic ecosystems and human health by biomagnification. Lake sediments can provide important historical information regarding changes in pollution levels and thus trace anthropogenic or natural influences. This research investigates the 100-year history of mercury (Hg) deposition in sediments from Chao Lake, a shallow eutrophic lake in China. The results indicate that the Hg deposition history can be separated into three stages (pre-1960s, 1960s–1980s, and post-1980s) over the last 100 years. Before the 1960s, Hg concentrations in the sediment cores varied little and had no spatial difference. Since the …

Resource Estimation And Simulation At West Butte In The Mcdonald Gold Deposit Near Lincoln, Montana, Jonathan Szarkowski

Graduate Theses & Non-Theses

The McDonald gold deposit is located in Lewis and Clark County near Lincoln, Montana and is divided into two regions: East Butte and West Butte. Approximately 90% of gold mineralization at McDonald is hosted by quartz-adularia-altered lithic tuff. Low-grade, stratabound, disseminated mineralization within permeable volcanic tuff is the dominant style of mineralization at McDonald. Higher-grade mineralization at West Butte is interpreted to be controlled by subvertical, intersecting vein systems that occur along the 9800’ E-W fault. Preliminary gold estimates at West Butte indicated the possibility of a 500 koz gold orebody at an average grade of 7.2 grams per ton …

Wall Control Blasting At The Orphan Boy Mine – Butte, Montana, Jewel Sakyi

Graduate Theses & Non-Theses

Blasting is often conducted to produce desirable fragment sizes to minimize production cost and energy consumption in downstream processes, including loading, hauling, and crushing. However, the venting of explosive energy in the rock formation sometimes causes unwanted damage beyond the desired perimeter of the blast area. Control blasting has mainly been used in surface mining operations to minimalize blast damage. To explore the applicability of control blasting in underground mining operations, protect the safety of students, faculty, and staff, prevent overbreak, and to ensure the stability of openings and workings, four experimental control blasts, comprising of three smooth blasts and …

Graduate Theses & Non-Theses

Exploration and Production companies are continually focusing more time, energy and resources into Extended Reach Drilling in order to maximize reservoir production while minimizing both environmental impact and development costs. These long laterals (2:1 Measured Depth: True Vertical Depth) are often more difficult to drill and can be severely impacted by inadequate drilling practices. Cuttings transport efficiency is a critical parameter of Extended Reach Drilling operations, and poor wellbore cleaning can lead to excessive torque, drag, and several other serious downhole problems.

Although many studies have been performed that identify the importance of drill string rotation on cuttings movement, there …

Geochemistry Of Metals And Nutrients In Fine-Sediment Pore Water In Blacktail And Silver Bow Creeks, Butte, Montana, Robert Radar

Graduate Theses & Non-Theses

Historical mining in Butte, Montana has impacted surface and groundwater in the area. Although most of the known sources of contaminants of concern have been removed or remediated, metal loading continues to occur in lower Blacktail Creek and upper Silver Bow Creek. Possible sources of metals include upwelling groundwater and interaction between the stream and metal-rich sediment in the stream bed. To assess the importance of fine sediment as a source (or sink) for metals, this investigation used sediment pore water diffusion samplers (“peepers”). Peepers are ideal for capturing cm-scale vertical gradients in pore water chemistry across the sediment-water interface. …
