Melanin (from the Greek μέλας, mélas, black) is a biopigment ubiquitous in flora and fauna, featuring broadband optical absorption, hydration-dependent electrical response, ion-binding affinity as well as antioxidative and radical-scavenging properties. In the human body, photoprotection in the skin and ion flux regulation in the brain are some biofunctional roles played by melanin. Here we discuss the progress in melanin research that underpins emerging technologies in energy storage/conversion, ion separation/water treatment, sunscreens, and bioelectronics. The melanin research aims at developing approaches to explore natural materials, well beyond melanin, which might serve as a prototype benign material for sustainable technologies.

“…To solve the problem, an alternative to form thin polymer¯lms was developed based on the oxidative self-polymerization of dopamine (3,4-dihydroxyphenylethylamine, DA) onto surfaces, which involves a single deposition process with control over¯lm thickness. DA, which was inspired by the composition of adhesive proteins in mussels, has been demonstrated to be an e®ective adhesive that can be attached to almost all material surfaces (metals, oxides, ceramics, 7 polymers, 8 carbon nanotubes, 9 magnetite nanoparticles (NPs) 10 and even te°on 11 ), and auto-polymerized to form polydopamine (PDA) coating in alkaline aqueous media. The process of preparing PDA is simple, less labor intensive, and the physicochemical properties can be well controlled by further chemical modi¯cation.…”

“…The shell thickness could be¯nely controlled in the range of 10-25 nm by varying the concentration of DA. 10 Another attractive class of porous material is metal-organic frameworks (MOFs). They have lots of applications in di®erent areas due to their extraordinary properties, including high surface area, plenty of Lewis acid sites, aromatic organic ligands, availability of in-pore, outersurface functionalization and excellent mechanical stability.…”

Polydopamine (PDA) capsule and core-shell structures with tailored structures and properties are of particular interests due to their multifunctions and potential applications as new colloidal structures in diverse¯elds. Among the available fabrication methods, PDA¯lm onto colloidal particles followed by selective template removal has attracted extensive attention due to its advantages of precise control over the size, wall thickness and functions of the obtained capsules. The past several years has witnessed a rapid increase of research concerning the new fabrication strategies, functionalization and applications of this kind of capsules and core-shell structures, particularly in many¯elds such as drug delivery, catalysis, antibacterial, etc. In this review, the very recent progress of the capsule and core-shell structures based on PDA are summarized. There are basically two sections, including the fabrication process of PDA capsules, core-shell structures, and the various applications based on PDA.

Nanoparticle drug delivery carriers, which can implement high performances of multi-functions, are of great interest, especially for improving cancer therapy. Herein, we reported a new approach to construct Mn 2+ -coordinated doxorubicin (DOX)-loaded poly(lactic- co -glycolic acid) (PLGA) nanoparticles as a platform for synergistic chemo-photothermal tumor therapy. DOX-loaded PLGA (DOX/PLGA) nanoparticles were first synthesized through a double emulsion-solvent evaporation method, and then modified with polydopamine (PDA) through self-polymerization of dopamine, leading to the formation of PDA@DOX/PLGA nanoparticles. Mn 2+ ions were then coordinated on the surfaces of PDA@DOX/PLGA to obtain Mn 2+ -PDA@DOX/PLGA nanoparticles. In our system, Mn 2+ -PDA@DOX/PLGA nanoparticles could destroy tumors in a mouse model directly, by thermal energy deposition, and could also simulate the chemotherapy by thermal-responsive delivery of DOX to enhance tumor therapy. Furthermore, the coordination of Mn 2+ could afford the high magnetic resonance (MR) imaging capability with sensitivity to temperature and pH. The results demonstrated that Mn 2+ -PDA@ DOX/PLGA nanoparticles had a great potential as a smart theranostic agent due to their imaging and tumor-growth-inhibition properties.
