Overoxidized polypyrrole/overoxidized poly(3,4-ethylenedioxythiophene)/graphene quantum dots-chitosan as enhanced electrochemical sensing platform for luteolin determination in peanut shells

Abstract

A novel electrochemical sensor was constructed based on an overoxidized polypyrrole / overoxidized poly(3, 4-ethylenedioxythiophene) /graphene quantum dots-chitosan composite films modified glass carbon electrode (oPPy/oPEDOT/ GQDs-CS/GCE), for the accurate determination...
