Abstract
CTAB surfactant was assembled on ssDNA film electrode by electrostatic attraction between CTAB and ssDNA. The self-assembly of CTAB on ssDNA formed the micellar bilayer. Pyridoxol anions adsorbed on the micellar bilayer resulted in a markedly enhanced sensitivity. Practical applicability can be realized by the direct assay of pharmaceutical samples.
