RFA: P3 Awards: A National Student Design Competition for Sustainability Focusing on People, Prosperity and the Planet (2011)
Research Category: Pollution Prevention/Sustainable Development , P3 Challenge Area - Water



Develop a novel biosensor that can sensitively detect low concentration of mercury to monitor mercury pollution in the Red River; Disseminate the knowledge of protection of natural water to the public by giving a series of seminars to K-12 schools and hosting workshops in the local community.


To highly amplify the mercury signal using two biological approaches – rolling circle amplification (RCA) and thymine-mercury ion- thymine (T-Hg2+-T) mismatch.

Expected Results:

1) accurate monitoring of the mercury level in the Red River water using the developed sensor; 2) preservation of the natural water sources; 3) increase public awareness of the harmfulness of the mercury pollution; and 5) improvement of the human health by the minimization of the mercury pollution.

Supplemental Keywords:

Sustainable water management, drinking water, water treatment
