A melanin-inspired robust aerogel for multifunctional water remediation

Materials Horizons, Journal Year: 2023, Volume and Issue: 10(3), P. 1020 - 1029

Published: Jan. 1, 2023

Solar-driven vapor generation has emerged as a promising wastewater remediation technology for clean water production. However, the complicated and diversified contaminants in still restrict its practical applications. Herein, inspired by melanin nature, robust aerogel was facilely fabricated multifunctional via one-pot condensation copolymerization of 5,6-dihydroxyindole formaldehyde. Benefiting from superhydrophilicity, underwater superoleophobicity, synergistic coordination effects, resulting not only showed excellent performances oil resistance oil-water separation ability, but also removed organic dyes heavy metal ions simultaneously. Moreover, owing to admirable light harvesting capacity porous microstructure fast transportation, aerogel-based evaporator exhibited an evaporation rate 1.42 kg m-2 h-1 with 91% efficiency under 1 sun illumination, which can be reused long-term evaporation. Note that such stable could maintained even containing complex multicomponent contaminants. Outdoor experiments lotus pond natural sunlight proved great potential All those features this all-in-one melanin-inspired may provide new strategies development photothermal devices solar-driven remediation.

Recent Applications of Melanin-like Nanoparticles as Antioxidant Agents

Antioxidants, Journal Year: 2023, Volume and Issue: 12(4), P. 863 - 863

Published: April 2, 2023

Nanosized antioxidants are highly advantageous in terms of versatility and pharmacokinetics, with respect to conventional molecular ones. Melanin-like materials, artificial species inspired by natural melanin, combine recognized antioxidant (AOX) activity a unique preparation modification. Due this documented biocompatibility, melanin has been incorporated into variety nanoparticles (NP) order give new platforms for nanomedicine enhanced AOX activity. In review article, we first discuss the chemical mechanisms behind materials context inhibition radical chain reaction responsible peroxidation biomolecules. We also focus briefly on properties melanin-like NP, considering effect parameters such as size, methods surface functionalization them. Then, consider most recent relevant applications NPs that able counteract ferroptosis be involved treatment important diseases affect, e.g., cardiovascular nervous systems, well kidneys, liver articulations. A specific section will dedicated cancer treatment, since role is still very debated. Finally, propose future strategies development better understanding materials. particular, composition structure these debated, they present high level variability. Thus, mechanism interaction nanostructures different radicals reactive would design more effective nano-agents.
