Electrochemical Detection Of Arsenic Using A Microfluidic Sensing Platform, Ben Demaree, Allie Sibole, Jessica Vandergiessen

Bioengineering Senior Theses

Arsenic contamination of groundwater is a global health problem affecting millions of people. Long-term exposure to arsenic has been linked to a variety of cancerous and non-cancerous health effects. Current diagnostic technologies for arsenic quantification are limited to either inaccurate colorimetric methods or expensive, off-site lab assays, which are unsuitable for resource-limited settings. To address this need for an affordable and rapid means of sensitive arsenic detection, our design project focuses on the design and fabrication of the first point-of-use microfluidic device capable of electrochemical detection and quantification of arsenic levels in groundwater sources. We fabricate our device rapidly and …
