Golf ball-like MoS 2 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...

| description | 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. Figures of merit for the resulting electrode include (a) a sensitivity of 6.24 μA·μM
·cm
, (b) a low working voltage (+0.17 V vs. Ag/AgCl), and (c) a low limit of detection (36 nM at S/N = 3). The electrode is selective over uric acid, reproducible and stable. It was applied to the determination of dopamine in spiked urine samples. The recoveries at levels of 10, 20 and 40 μM of DA are 101.6, 99.8 and 107.8%.
