SH-β-CD-Gr/PdNPs were firstly synthesized in one step.
SH-β-CD was employed as a multifunctional molecule.
SH-β-CD-Gr/PdNPs can act as enhanced material for electrochemical detection of rutin and isoquercitrin.
The method has high sensitivity, good stability and broad linear range.
The approach is highly simple and cost-efficient.
