Conjugated polyelectrolyte complexes with single-walled carbon nanotubes for amperometric detection of glucose with inherent anti-interference properties

Supramolecular complexes between single-walled carbon nanotubes and the conjugated polyelectrolytes poly[3-(3-N,N-diethylaminopropoxy)thiophene] (PDAOT), poly[3-(3′-thienyloxy)propanesulfonate] (P3TOPS), and poly[2,5-bis(3-sulfonatopropoxy)-1,4-ethynylphenylene-alt-1,4-ethynylphenylene] (aPPE) were prepared in homogeneous aqueous solution, and mixed with the enzyme glucose oxidase. The resulting solutions were drop cast onto the surface of …
