1D MWCNTs bridged 2D Pdop@GR form 3D Pdop@GR/MWCNTs nanocomposites as electrode material.
Modifying the outer surface of GR with polydopamine was rarely reported.
This easy approach can promote the practically wide applications of GR.
The overlapping voltammetric response of DA and UA is well-resolved in the presence of AA.
