“…Additionally, with the help of molecular dynamic simulations, it has been theorized that the air-water surface works as a template playing a significant role in stacking PDA tetramers (Figure 4a). [95] Electrochemically grown films have been studied in detail in the literature, with some important insights on the polymerization provided recently by Olejnik et al in their study. They found that catechol units are more likely polymerized than quinone forms.…”

Photocatalysis can be understood as the acceleration of chemical reactions by incident light, especially when the catalyst is photoactive. These reactions are unachievable or very difficult without photoactivation. Photocatalysis could find applications in a wide range of fields such as renewable energy (water splitting, CO 2 reduction, solar fuel production) and environmental (water treatment by removing pharmaceutic and pesticides contaminant, for instance, and improving air quality by reducing volatile organic compounds [VOCs]). [1] The advance in the photocatalysis field is driven by developing novel, innovative materials that mainly allow light absorption and efficient charge separation. [2] The most developed photocatalysts are inorganic semiconductors such as metal oxides (such as ZnO, TiO 2 , WO 3 , SnO 2 , and CuO) [3,4] and chalcogenides (ZnS, CuS, CdS, Sb 2 S 3 , Cu 2 SnS 3 , and Cu 2 SnSe 3 ). [5,6] In order to enhance the performance of these semiconductor catalysts, different strategies were investigated to reduce the recombination of photogenerated electron-hole pairs and to extend the absorption edge of these catalysts to the visible region of sunlight: 1) tuning of the morphologies, 2) doping to tune the bandgap, 3) junction between several semiconductor materials, [7,8] and 4) combining with metallic and plasmonic nanomaterials (Cu, Pt, Au, Pd). [9,10] An alternative approach to increase the efficiency of these photocatalysts is the design of organic-inorganic hybrid materials. Two classes of hybrid materials were largely investigated: 1) small molecules such as dyes and molecular catalysts known for their sensitizing and photocatalytic properties, and 2) organic macromolecules or polymers are known for tuning the properties of the semiconductor. These polymers also act as a protective layer, tuning the composites' hydrophobicity/hydrophilicity or lipophilicity. Moreover, they could also provide additional photocatalytic, electron transferring, and conductive properties.Different types of polymers were investigated in the literature, such as polydopamine (PDA), polyaniline (PANI), polythiophene, poly(3-hexilthiophene) (P3HT), polyphenylenevinylenes (PPVs), poly(3,4-ethelenedioxythiophene) (PEDOT), chitosan (CS), poly(pyrrole) (PPy), polyvinyl alcohol (PVA), covalent organic polymer (COP), and covalent organic frameworks (COFs). [11] Two of the most well-established aforementioned conductive polymers are CS and PANI. Despite more than a century of ongoing research, these polymers continue to have a large and highimpact on the literature, as shown by the constantly growing research works published each year. This ever-increasing attention is primarily attributed to the extensive application of both

The biomaterials’ success within the tissue engineering field is hinged on the capability to regulate tissue and cell responses, comprising cellular adhesion, as well as repair and immune processes’ induction. In an attempt to enhance and fulfill these biomaterials’ functions, scholars have been inspired by nature; in this regard, surface modification via coating the biomaterials with polydopamine is one of the most successful inspirations endowing the biomaterials with surface adhesive properties. By employing this approach, favorable results have been achieved in various tissue engineering-related experiments, a significant one of which is the more rapid cellular growth observed on the polydopamine-coated substrates compared to the untreated ones; nonetheless, some considerations regarding polydopamine-coated surfaces should be taken into account to control the ultimate outcomes. In this mini-review, the importance of coatings in the tissue engineering field, the different types of surfaces requiring coatings, the significance of polydopamine coatings, critical factors affecting the result of the coating procedure, and recent investigations concerning applications of polydopamine-coated biomaterials in tissue engineering are thoroughly discussed.

Design and implementation of functional coatings is a topic of active research in a variety of health‐related applications, most of which require wet adhesion. The powerful wet adhesion of mussel byssus proteins rich in DOPA and lysine residues provided a clue to realize that the combination of a catechol and an amine component has a specific role in the interfacial adhesion. From this natural model, polydopamine (PDA)‐based coatings have been developed that result from the oxidative polymerization of dopamine combining the catechol and amine functionalities in the same molecule. Covalent interactions resulting from Michael‐type addition or Schiff‐base formation of the polymeric products from dopamine oxidation as well as non‐covalent π‐stacking and cation‐π interactions exemplify the diverse mode of catechol/amine interplay that have been identified as responsible of the adhesion and cohesion properties of PDA. In the last decade coatings inspired to the same chemistry but using different starting materials have been explored particularly catechols of natural origin and different amine components, while mechanistic studies with model compounds have allowed to rationalize the structural requirements for adhesion and to expand the potential of these functional coatings.
