Selenium-containing block copolymers and their oxidation-responsive aggregates
Abstract
A selenium-containing amphiphilic block copolymer (PEG-PUSe-PEG) with a hydrophobic polyselenide block and two hydrophilic poly(ethylene glycol) (PEG) blocks was synthesized via polymerization of toluene diisocyanate (TDI) with monoselenide-containing diols and subsequent termination with PEG monomethylether. PEG-PUSe-PEG is able to self-assemble in aqueous solution to form block copolymer aggregates. Interestingly, it was found that the aggregates have a good oxidation-responsiveness and undergo a structural dissociation in a mild oxidative environment (such as 0.1% H2O2 v/v) due to the unique sensitivity of selenide groups in presence of oxidants. Compared with the sulfide analogue PEG-PUS-PEG, PEG-PUSe-PEG is more sensitive to oxidants. It is anticipated that selenium-containing block copolymer aggregates may find application in the field of drug delivery systems.

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.
