Perspectives on poly(dopamine)
Abstract
Poly(dopamine) has emerged in recent years as a readily accessible synthetic analogue of the naturally occurring melanins. However, the polymer's structure has proved difficult to unambiguously elucidate and a variety of models have been proposed. Despite these challenges, poly(dopamine) has found extraordinary utility in a range of applications including surface coatings, biotechnology and biomedicine, and water purification membranes. Most of these applications take advantage of the robust polymer films that deposit onto a wide range of surfaces, as well as its inertness to harsh chemical environments. In view of the expansion of interest in poly(dopamine), we provide perspective on this material, focusing on its history, chemical relationship to melanins, recent applications, and potential areas for future study.

The adhesive mechanism of PDA on the interface of various substrates still remains debating due to the complexities of structural analysis of PDA and its analogous molecules such as eumelanin.

The second model is the "noncovalent bonding (quinhydrones)" polymerization fashion where DA monomers are linked together by noncovalent interaction including hydrogen bonding, charge transfer, ionic interaction, and π-stacking to aggregate into a structural macroassembly.

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.
