Nature-inspired phenolic chemistries have substantially nourished the engineering of advanced materials for widespread applications in energy, catalysis, and biomedicine, among others. To achieve predictable yet adaptable material structures and properties, the spatial and/or temporal control over the phenolic chemistries per se is increasingly demanded. In this review, a systematic overview of recent strategical advances in the spatiotemporal control of phenolic chemistries in materials science is given. The chemical diversity and reactivity of catechols and polyphenols are first introduced as phenolic building blocks. With a main focus on catechols (especially dopamine), renewed insights into their mechanisms of polymerization/assembly, adhesion, and cohesion are provided. The conditions for tuning phenolic polymerization/assembly are also outlined. This paper focuses on the latest strategies for imparting controlled manipulation of phenolic chemistries in terms of many aspects: growth kinetics, chemical compositions and structures, dimensions and architectures, spatial patterns, and surface functionality. Finally, critical issues facing this field with perspectives delivered on future research are discussed. As envisaged, this review will provide helpful guidance to orchestrate state-of-the-art phenolic chemistries and materials science for producing materials with intended, application-oriented properties and functions.

“…A multitude of reviews on melanins exist, covering various aspects of their biochemistry, functions, and applications. [ 47,57,59,71–82 ] This review focuses on the application of analytical techniques to study melanins in multidisciplinary contexts with a view to their use as sustainable resources for advanced biotechnological applications. The scope of the literature prevents this from being comprehensive in coverage, however, we have attempted to ensure it covers a wide variety of analytical techniques applied to melanins, highlighting a few examples of the insights drawn from analysis of melanins [ 83 ] and their precursors produced by bacteria and eukarya (including laboratory‐based scientists and engineers).…”

Melanins are a class of biopolymers that are widespread in nature and have diverse origins, chemical compositions, and functions. Their chemical, electrical, optical, and paramagnetic properties offer opportunities for applications in materials science, particularly for medical and technical uses. This review focuses on the application of analytical techniques to study melanins in multidisciplinary contexts with a view to their use as sustainable resources for advanced biotechnological applications, and how these may facilitate the achievement of the United Nations Sustainable Development Goals.

“…Melanin is a biopolymer derived from natural sources, so that it shows good biocompatibility and biostability. The first term can be defined as the absence of side effects, including cytotoxicity and antigenic response, when it is added to cell culture [ 7 , 8 , 9 ] or injected to living organisms [ 10 ], and the second, as the relative long life due to the absence of specific melanin-degrading enzymes in living cells, On the other hand, melanin shows a series of useful physicochemical properties, including a broadband absorption for UV–Vis–infrared radiations, hybrid ionic–electronic conductance, metal chelation, free radical scavenging capacities, redox reversibility [ 11 , 12 , 13 ], easy and cheap availability, and chemical versatility by conjugation with other molecules. In this context, natural and synthetic melanin-like molecules are excellent candidates with unique properties for biotechnological applications [ 14 , 15 ].…”

The huge development of bioengineering during the last years has boosted the search for new bioinspired materials, with tunable chemical, mechanical, and optoelectronic properties for the design of semiconductors, batteries, biosensors, imaging and therapy probes, adhesive hydrogels, tissue restoration, photoprotectors, etc. These new materials should complement or replace metallic or organic polymers that cause cytotoxicity and some adverse health effects. One of the most interesting biomaterials is melanin and synthetic melanin-related molecules. Melanin has a controversial molecular structure, dependent on the conditions of polymerization, and therefore tunable. It is found in animal hair and skin, although one of the common sources is cuttlefish (Sepia officinalis) ink. On the other hand, mussels synthesize adhesive proteins to anchor these marine animals to wet surfaces. Both melanin and mussel foot proteins contain a high number of catecholic residues, and their properties are related to these groups. Dopamine (DA) can easily polymerize to get polydopamine melanin (PDAM), that somehow shares properties with melanin and mussel proteins. Furthermore, PDAM can easily be conjugated with other components. This review accounts for the main aspects of melanin, as well as DA-based melanin-like materials, related to their biomedical and biotechnological applications.
