A simple and inexpensive methodology was used to develop a novel electrochemical
sensor for the determination of Sudan II. The interaction of Sudan II with salmon sperm ds-
DNA on the surface of salmon sperm ds-DNA-modified pencil graphite electrode (PGE) and
in solution phase was studied, using differential pulse voltammetry. The difference between
adenine and guanine signals of the ds-DNA after and before interaction with Sudan II was
directly proportional to Sudan II concentration, which used for quantitative inspections. ...
