A new molecularly imprinted polymer–multiwall carbon nanotube paste electrode (MIP–
MWNPE) was prepared as a voltammetric sensor for rutin. The electrochemical behavior of
rutin at the surface of the modified electrode was studied using cyclic voltammetry (CV) and
square wave voltammetry (SWV). Under the optimized conditions, the oxidation peak current
of rutin showed two linear dynamic ranges (0.08–1.4 mM and 2.0–160.0 mM) with a
detection limit of 0.05 mM, using square wave voltammetric method. The RSD% for 5.0 ...
