Multifunctional NIR-Triggered Nanozyme-Based Microneedles for Synergistic Eradication of MRSA and Enhanced Wound Healing

This study found that a newly created biomimetic microneedle platform effectively expedited wound repair in diabetic animal models by reducing inflammation, enhancing angiogenesis, and promoting skin regeneration through targeted drug delivery and immune response modification.

In this study, a self-adaptive nanozyme embedded in a madecassoside-enriched hydrogel demonstrated strong antibacterial efficacy and accelerated healing in wounds infected with drug-resistant bacteria, as evidenced by improved repair and regeneration in MRSA-infected mice and preclinical pig models.

This study found that nanofibers combining a polydopamine coating and curcumin nanocrystals were effective in treating diabetic wounds infected with methicillin-resistant Staphylococcus aureus by providing sequential photothermal antibacterial action and promoting M2 macrophage polarization, which accelerated wound healing through enhanced angiogenesis and cell proliferation.

This study proposes a metal-organic gel-encapsulated microneedle system with antibacterial, anti-inflammatory, and pro-angiogenic properties for treating infected wounds, demonstrating potential for precise and adaptive management by targeting various stages of wound healing.

The microneedle arrays effectively promote wound healing and have potential for clinical use.
