Skin and soft-tissue infections require significant consideration because of their prolonged treatment duration propensity to rapidly progress, resulting in severe complications. The primary challenge stems from the involvement drug-resistant microorganisms that can form impermeable biofilms, as well possibility infection extending deep into tissues, thereby complicating drug delivery. Dissolving microneedle patches are an innovative transdermal drug-delivery system effectively enhances penetration through stratum corneum barrier, increasing concentration at site infection. They offer highly efficient, safe, patient-friendly alternatives conventional topical formulations. This comprehensive review focuses on recent advances emerging trends dissolving-microneedle technology for antimicrobial skin-infection therapy. Conventional antibiotic microneedles compared with those based agents, such quorum-sensing inhibitors, peptides, antimicrobial-matrix materials. also highlights potential incorporating chemodynamic, nanoenzyme antimicrobial, photodynamic, photothermal antibacterial therapies. explores advantages various therapies emphasizes combined application improve efficacy microneedles. Finally, this analyzes druggability different discusses possible future developments.

Abstract The healing of bacterial biofilm‐infected wounds is a complex process, and the construction emerging therapeutic modalities that regulate microenvironment to magnify effects reduce biotoxicity still highly challenging. Herein, an engineered microneedle (MN) patch reported mediate efficient delivery black phosphorus nanosheets (BP NSs) copper peroxide nanodots (CP NDs) for dual nanodynamic sterilization methicillin‐resistant staphylococcus aureus (MRSA)‐infected wound healing. Results demonstrate system can eliminate biofilm, cytotoxicity, promote angiogenesis tissue regeneration by multiple advantages chemodynamic therapy (CDT), enhanced photodynamic (PDT), improved degradation process from BP NSs phosphate promoting cell proliferation. Notably, balance between excellent stability rapid degradability maintained, mechanism vividly elucidated density functional theory (DFT)‐based molecular dynamics (MD) calculations. Furthermore, transcriptional changes treated MRSA‐infected skin are studied using RNA‐seq technology reveal potential mechanism. As envisaged, proposed MN provides safe, easy, also effective approach achieve temporal regulation wounds.

Abstract Chronic nonhealing wounds, common in diabetic patients, represent a major clinical challenge, causing significant morbidity and healthcare costs. Persistent bacterial biofilms are critical obstacle to wound healing, necessitating their effective elimination promote rapid recovery. In photodynamic antimicrobial therapy (PDAT), enhancing the interaction between photosensitizer is key achieving efficient antibiofilm effects. Here, novel dissolvable microneedle patch containing benzoxaborole ( BOB )‐functionalized designed, TPI‐BOB , for bacteria‐specific targeting localized PDAT of multidrug‐resistant biofilm infections wounds. integrates moiety selective binding pyridine‐based cationic group enhance electrostatic interactions, showing superior activity Gram‐positive bacteria, particularly MRSA . To further optimize therapeutic delivery combat biofilm‐associated infections, incorporated into microneedles, which rapidly disintegrate upon application sites. This system facilitates localized, biofilms, where it triggers action under white‐light irradiation. treatment eradicates biofilm, initiating tissue repair that reduces inflammation, promotes collagen deposition, stimulates angiogenesis, accelerating healing. work presents strategy combining with microneedle‐mediated drug delivery, offering promising approach treating wounds other biofilm‐related infections.
