摘要：
The interaction of 4-nonylphenol (NP) with deoxyribonucleic acid (DNA) was explored electrochemically by using differential pulse voltammetry (DPV) in combination with unmodified and modified pencil graphite electrodes (PGE) with sink walled carbon nanotubes (SWCNT) The differentiation of the two oxidation signals coming from NP and DNA base, guanine was studied before and after the interaction process In addition, the effect of NP concentration was investigated in order to determine the optimum experimental conditions. The detection limit and the reproducibility were determined by using CNT-modified electrodes.
