Abstract
Aims: Helicobacter pylori (HP) DNA was assayed using a newly fabricated voltammetric handheld circuit equipped with an interfaced graphite pencil electrode (PE) sensor. Methods: Under optimum analytical parameters, the square-wave (SW) stripping detection range attained was 0.1-0.7 mg/L. Results: A relative standard deviation of 1.68% (RSD, n=5) was observed at a 3.2mg/L HP DNA within a 90s accumulation time. Under these conditions, the analytical detection limit approached 0.07 mg/L. Conclusions: The developed methods can be applied to HP assays of preliminary stage gastric cancer patient tissues.
