Abstract
Fabrication of multicomponent nanocomposites as electrodemodified materials is an effective strategy to design highly active electrochemical sensors Here we present a facile strategy to fabricate the palladium phthalocyaninemultiwalled carbon nanotube PdPcMWCNTs nanocomposite for the sensitive detection of rutin Results showed that the prepared nanocomposites exhibited excellent electrocatalytic activity toward rutin due to the synergetic effects of PdPc and MWCNTs excellent electric conductivity and catalytic activity and the homogeneous dispersibility of Nafion Under the optimized conditions the developed sensor exhibited a linear response range from 010 to 51 μM for rutin with a low detectable limit of 75 nM and a fast response less than 30 s The proposed method might offer a possibility for electrochemical analysis of rutin in Chinese medical analysis or serum monitoring owing to its low cost simplicity high sensitivity good stability and few interferences against common coexisting ions in real samples
