     In the last few years, transition metal disulphide materials (2D-TDMs) have received a fast growing interest due to their unique properties which are expected to open novel applications of these nanomaterials in many advanced fields. Among these, MoS2 nanosheets have sizable band gap and two-dimension size which offer high surface area which favors the electron and mass transfer, allowing applications in electrochemical sensing. 

​

     In this work, 2D-MoS2 nanosheets were investigated to detect by a non-enzymatic electrochemical sensor dopamine (DA), a precursor of norepinephrine, that acts as a neurotransmitter at certain synapses of the brain. Disorders at these synapses have been implicated in schizophrenia and Parkinson disease. Further aim of this work was detect dopamine also in presence of uric acid (UA) and tyrosine (Tyr).
