Golf ball-like MoS nanosheet arrays anchored onto carbon nanofibers for electrochemical detection of dopamine.

Arrays of molybdenum(IV) disulfide nanosheets resembling the shape of golf balls (MoS NSBs) were deposited on carbon nanofibers (CNFs), which are shown to enable superior electrochemical detection of dopamine without any interference by uric acid. The MoS NSBs have a diameter of ∼ 2 μm and are made up of numerous bent nanosheets. MoS NSBs are connected by the CNFs through the center of the balls.
