Microfluidic device for arsenic detection
- Detailed Technology Description
- The technology relates to paper-based devices with a gold nanosensor that detects if the arsenic level of a sample exceeds 10 μg/L. The technology was designed so as to eliminate interference from naturally occurring metal ions.
- *Abstract
-
The research led by Dr. Brendan MacDonald has led to a novel technology that enables users rapidly and reliably detect if arsenic contamination exists and if it exceeds or is below the WHO guideline levels of 10 μg/L. The technology is a microfluidic paper-based analytical device (μPAD) with a gold nanosensor functionalized with a α-lipoic acid and thioguanine (Au-TA-TG) that allows cost effective detection of arsenic. The technology was designed so as to eliminate any interference that could result from naturally occurring metal ions. Interference is prevented by using a specific pH value on the paper tests. The test strips are T-shaped and provide a red to black color change.
