Melanoma, the most lethal skin disease with steadily rising incidence rates, demands safer, more precise, and intelligently effective combination therapies. By utilizing traditional Chinese medicine polysaccharides as the microneedle matrix, we developed dual-layer microneedles incorporating multi-core–shell structured nanoparticles and anti-inflammatory immune nanoparticles loaded with both chemical and herbal components. These dual-layer microneedles demonstrate superior synergistic antitumor and anti-inflammatory effects both in vivo and in vitro. Following local administration, they achieve a 95.6% inhibition rate against melanoma, effectively inhibiting tumor growth and invasion. They significantly enhance the activation and immune function of tumor-targeting T cells, increase the proportion of CD8 + T cells, and simultaneously activate innate immune functions in immune organs. This approach boosts the proportion of immune T cells and NK cells in the spleen, promotes T cell secretion of TNF-α to achieve anti-tumor immune activation, and enhances systemic anti-inflammatory immune responses. Simultaneously, it reduces drug concentration in non-targeted areas, minimizing systemic toxicity and side effects. This achieves a tiered drug delivery effect combining “chemotherapy-immunotherapy-anti-inflammation,” realizing a three-pronged synergistic anti-tumor effect through “break the skin barrier −drug release-immune coordination.” It provides a reference for developing new formulations for microneedle local administration and topical anti-tumor preparations.","PeriodicalId":101318,"journal":{"name":"MATERIALS & DESIGN","volume":"262 1","pages":"115559-115559"},"PeriodicalIF":0.0,"publicationDate":"2026-01-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147381654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Wound self-repair is prone to forming hard-to-heal chronic wounds due to infections, vascular damage, diabetes and other factors. Selecting the appropriate treatment and dressing can help prevent the deterioration of chronic wounds and facilitate the restoration of normal structure and function. Carboxymethyl chitosan (CMCS)-modified hydrogels can promote tissue repair, while human umbilical vein endothelial cell derivatives (ECd) enhance self-repair. In this study, ECd was prepared into lyophilized powder using vacuum freeze-drying to preserve its original active ingredients. In vitro experimental results revealed that a specific concentration of ECd effectively supported cell proliferation, migration and angiogenesis. ECd was further encapsulated in the designed glycidyl methacrylate-modified carboxymethyl chitosan (M−CMCS) hydrogel. The optimal combination of ECd and M−CMCS hydrogel (ECd@M−CMCS) was evaluated by testing the material properties, analyzing cellular behaviors and assessing antimicrobial effects. Sprague Dawley rat models (tail-breaking, liver incision, skin whole-layer defect) demonstrated ECd@M−CMCS exhibited good biocompatibility and enhanced wound healing and hemostasis in vivo .","PeriodicalId":101318,"journal":{"name":"MATERIALS & DESIGN","volume":"260 1","pages":"115242-115242"},"PeriodicalIF":0.0,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147332272","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To disrupt the pathogenic cycle of inflammation and oxidative stress driving intervertebral disc degeneration (IDD), we engineered a hierarchical micro-nano therapeutic platform (CPM). This system integrates Chondroitin sulfate methacrylate (ChsMA) hydrogel microspheres mimicking the extracellular matrix (ECM), Pluronic F-127 nanoparticles encapsulating anti-inflammatory puerarin for sustained release (52.6 % over 28 days), and a metal-phenolic network (MPN) “armor” of tannic acid (TA) and strontium ions (Sr 2+ ) providing broad-spectrum reactive oxygen species (ROS) scavenging (>83 % clearance) and enzyme-mimetic activity. CPM synergistically neutralizes oxidative stress, suppresses inflammation, and protects ECM integrity. In vitro, CPM demonstrates excellent biocompatibility and multi-target efficacy, concurrently suppressing inflammation, scavenging ROS, restoring mitochondrial function, and promoting ECM regeneration in stressed nucleus pulposus cells. In a rat IDD model, a single minimally invasive injection of CPM provides sustained drug retention (38.1 % at 2 weeks), preserves disc structure and proteoglycan content, and restores T2-MRI signals. This triple-synergistic strategy represents a promising therapeutic paradigm for arresting IDD progression.","PeriodicalId":101318,"journal":{"name":"MATERIALS & DESIGN","volume":"260 1","pages":"115243-115243"},"PeriodicalIF":0.0,"publicationDate":"2025-11-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330606","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chronic diabetic wounds (CDWs) are refractory lesions characterized by oxidative stress, persistent infection, inflammation, ischemia, and excessive advanced glycation end products (AGEs). Binding of AGEs to their receptor (RAGE) triggers inflammatory and oxidative pathways, reinforcing a vicious cycle that impedes healing. Here, we developed a multifunctional hydrogel by crosslinking aldehyde-rich MnO 2 @protocatechualdehyde (PCA) nanoparticles with quaternized carboxymethyl chitosan (QCMC) via a Schiff base reaction, incorporating molybdenum disulfide (MoS 2 ) quantum dots. This hydrogel exhibits antibacterial activity, scavenges reactive oxygen species (ROS), reduces AGEs and RAGE expression, alleviates hypoxia, and promotes angiogenesis. In vitro and in vivo experiments demonstrated that it effectively inhibits bacterial growth, mitigates inflammation, enhances neovascularization, and accelerates CDW healing. This work offers a promising strategy for multi-target regulation of diabetic wound microenvironments.","PeriodicalId":101318,"journal":{"name":"MATERIALS & DESIGN","volume":"260 1","pages":"115165-115165"},"PeriodicalIF":0.0,"publicationDate":"2025-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147330566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
