Abstract

Nanocomposite of β-cyclodextrin and graphene sheet (β-CD/GS) was successfully prepared, which exhibited high stability in aqueous solution. When used in electrochemical detection of dopamine, the β-CD/GS modified carbon electrode showed low detection limit, broad linear range, along with good ability to suppress the background current from large excess ascorbic acid. The electrochemical reaction of dopamine on the β-CD/GS showed a mass diffusion-controlled process, which was different from the adsorption-controlled process on the unmodified graphene sheet.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
