Electrochemical sensor based on a three dimensional nanostructured MoS nanosphere-PANI/reduced graphene oxide composite for simultaneous detection of ascorbic acid, dopamine, and uric acid.

A three dimensional (3D) nanostructured composite based on the self-assembly of MoS nanospheres and polyaniline (PANI) loaded on reduced graphene oxide (denoted by 3D MoS-PANI/rGO) was prepared a feasible one-pot hydrothermal process. The 3D MoS-PANI/rGO nanocomposite not only exhibits good functionality and bioaffinity but also displays high electrochemical catalytic activity. As such, the developed 3D MoS-PANI/rGO nanocomposite can be employed as the sensing platform for simultaneously detecting small biomolecules, , ascorbic acid (AA), dopamine (DA), and uric acid (UA).
