       Biosensor
       Based on reverse engineering principles, we
   engineered our bacteria into valid bioreporters
   for Hg(II) in aquatic environment. Rational desi-
   -gn of genetic circuit topology was conducted to
   confer mercury sensor and regulator compone-
   -nts high efficiency and robustness. Additionally,
    a new approach based on the use of multiple
   bioreporter cell lines to control assay variations
   and to improve in field application ease was also
   developed.
