“…[58,79] Polydopamine, a synthetic melanin analog, has been used to selectively extract and separate metal cations from aqueous solutions, leveraging on the different binding affinities of the pigments toward different cations. [67,100,101] Films of polydopamine can reduce Ag + cations into Ag nanoparticles, which impart antibacterial properties to the same films. [83] Self-assembled molecular networks of indole-2-carboxylic acid (I2CA, i.e., melanin's monomer DHICA lacking the two hydroxyl phenolic groups) have been investigated on Au (111) surfaces: I2CA showed, both in ultrahigh vacuum and at liquid/solid interfaces, hydrogen-bonded assemblies from molecular dimers, [102] the next step being the same study with DHI and DHICA.…”

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.

“…Farnad's groups have directed the use of polydopamine nanoparticles as an adsorbent for copper ions from wastewater [20]. However, significant limitations, including the very high cost of dopamine material and the ineffective use of the interior of polydopamine microspheres hinder their commercialization and industrialization on a large scale.…”

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.
