Abstract: A novel electrochemical sensor using the molecularly imprinted (MIP) oxygen-containing polypyrrole (PPy) decorated carbon nanotubes (CNTs) composite was proposed for in vivo detection of dopamine (DA). The prepared sensor exhibits a remarkable sensitivity of (16.18 μA/μM) with a linear range of 5.0 x 10-11 - 5.0 x 10-6 M and limit of detection as low as 1.0 x 10-11 M in the detection of DA, which might be due to the plenty cavities for binding DA through π - π stacking between aromatic rings and hydrogen bonds between amino groups of DA and oxygen-containing groups of the novel PPy
