| Abstract | The low electronic conductivity limits the application of molybdenum disulfide (MoS2) in electrochemical sensing field, let alone the label-free and self-signal amplification DNA sensing. Aiming at this problem, a novel polyaniline-molybdenum disulfide (PANI-MoS2) nanocomposite through a facile oxidation polymerization aniline monomer on the thin-layer MoS2 matrix is prepared, which is preobtained via a simple ultrasonic exfoliation method. It is generally appreciated that conducting polymers, e.g., polyaniline (PANI), can work as a direct transducer based on themselves-signal without any label or indicator. Moreover, MoS2 not only serves as an excellent conductive skeleton provided a high electrolytic accessible surface area for redox-active PANI, but also supports a direct path for electron transfer. Therefore, the hybrid of PANI and MoS2 exhibits superior electrochemical performance to pure PANI and MoS2, and can be considered as a superior candidate for direct and label-free electrochemical DNA sensing. A series of experiments are performed to investigate the effect of synthetic conditions (component, dosage of MoS2, and reaction time) on probe DNA (pDNA) immobilization and hybridization adopting the PANI self-signal as the measure signal. The results show that the dosage of MoS2 has a more influence on pDNA immobilization and hybridization. |
