Cuttlefish Ink‐Derived Melanin/MXene Composites: Boosting Stability and Unleashing Synergistic Photothermal‐Mechanical Antimicrobial Effects Against Biofilms
The researchers present CI@MXene, a core‑shell nanohybrid that encapsulates natural cuttlefish ink melanin within MXene nanosheets, creating a protective barrier that stops oxidation and reduces cytotoxicity. Under near‑infrared light the composite delivers mild photothermal therapy—keeping skin temperature below 45 °C—while preserving MXene’s nano‑knife effect, achieving over 95 % killing of E. coli and S. aureus and roughly 80 % disruption of mature biofilms. In a murine wound‑infection model, CI@MXene accelerated wound closure, markedly lowered bacterial burden, and dampened inflammatory responses, demonstrating a stable, biosafe antibacterial platform.
Deciphering Emergent Oxyhalide Solid‐State Electrolytes for Next‐Generation All‐Solid‐State Lithium Metal Batteries
All‑solid‑state lithium metal batteries (ASSLMBs) are emerging as a safer, higher‑energy alternative to conventional lithium‑ion cells, but their commercial rollout hinges on solid‑state electrolytes (SSEs) that combine high ionic conductivity with stability. Halide‑based SSEs have attracted attention for their excellent...
