Optical Detection of Mercury(II) in Aqueous Solutions by Using Conjugated Polymers and Label‐Free Oligonucleotides
Abstract
A conjugated-polymer-based “mix-and-detect” optical sensor for mercury ions is fabricated by using a water-soluble poly[3-(3′-N,N,N-triethylamino-1′-propyloxy)-4-methyl-2,5-thiophene hydrochloride] (PMNT) and a label-free, mercury-specific oligonucleotide (MSO) probe. PMNT binds to the Hg2+-free MSO and the Hg2+–MSO complex in different ways, and exhibits distinguishable and specific optical responses to the target-induced conformation change.

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.
