2013年7月22日 · Polydopamine (PDA) formed by the oxidation of dopamine is an important polymer, in particular, for coating various surfaces. It is composed of dihydroxyindole, indoledione, and dopamine units, which are assumed to be covalently linked. Although PDA has been applied in a manifold way, its structure is still under discussion.

2023年2月7日 · Polydopamine is a biomimetic self-adherent polymer, which can be easily deposited on a wide variety of materials. Despite the rapidly increasing interest in polydopamine-based coatings, the...

The PDA structure remains controversial and the polymerization mechanism is still discussed [32,33,34]. However, there is a consensus that the polymerization mechanism, kinetics, shape, and structure of PDA strongly depend on the mode …

Polydopamine (PDA) is a polymer that derives from the self-polymerization of the biomolecule dopamine. It can be easily synthesized to obtain spherical nanoparticles (PDNPs), tunable in terms of...

2019年5月7日 · Polydopamine (PDA) is a polymer easily obtained by oxidation of dopamine. It is composed of indole and dopamine units in various oxidation states and to a lesser extent of pyrroles. It adheres to all type of surfaces even under water due to its abundant catechol moieties assisted by amino groups.

2023年9月11日 · This paper mainly focuses on the morphology and structure regulation and related applications of polydopamine-based nanostructures, including zero-dimensional (quantum dots), one-dimensional (nanotubes, nanorods, nanoribbons, nanofibers), two-dimensional (nanosheets, microfilms), three-dimensional (nanospheres, nanoflowers), and other ...

Structurally, polydopamine is very similar to melanin, which is a pigment of human skin responsible for the protection of underlying skin layers by efficiently absorbing light with potentially harmful wavelengths.

2013年7月22日 · Polydopamine (PDA) formed by oxidation of dopamine is an important polymer in particular for coating various surfaces. It is composed of dihydroxyindole, indoledione and dopamine units, which are...

Using an integrated chemical and spectroscopic approach enables the demonstration of: a) a three‐component structure of polydopamine, comprising uncyclized (catecholamine) and cyclized (indole) units, as well as novel pyrrolecarboxylic acid moieties; b) remarkable variations in the relative proportions of the cyclized and uncyclized units ...
