Abstract

Nanosheet like nickel metal organic frameworks (Ni-MOFs) have been synthesized using solvothermal route at room temperature. Functionalized multiwalled carbon nanotubes (MWCNTs) have been embedded into these MOFs through equilibration to prepare the composite. The composite (Ni-MOFs/MWCNTs) has been used as a modifier in sensor fabrication on glassy carbon electrode surface and successfully applied in dopamine measurement through cyclic voltammetry and square wave voltammetry techniques. The composite has exhibited enhanced electrochemical performance with a very low detection limit of 0.017 μM. The protocol showed wide linearity in the concentration range 2–200 μM with a sensitivity of 17.14 μAμM−1cm−2. The proposed electrochemical platform exhibited high sensitivity and selectivity in dopamine sensing which has been successfully applied to real sample matrices like human blood serum and injection.
