ABSTRACT This review aims to provide a comprehensive analysis of recent advancements in smart microneedles (MNs) within the biomedical field, focusing on integration stimuli‐responsive polymers for enhanced therapeutic and diagnostic applications. Conventional drug delivery methods are known face limitations precision, safety, patient compliance, which can be addressed by innovative features MNs. Through use various polymers, these MNs have been designed react environmental or physiological cues, allowing on‐demand release, biomarker sensing, localized interventions. Fundamental materials used fabrication MNs, including metals, composite hydrogels, reviewed, different categories stimuli‐responsiveness, such as photo, electro, thermal, mechanical, biochemical, explored. Application‐specific designs areas delivery, cancer therapy, diabetes management, skin disease treatments also examined. this discussion, it is highlighted that poised play significant role advancing personalized noninvasive medical treatments.

The skin, our first line of defense against external threats, combines a physical barrier and rich microbial community. Disruptions this community, for example, due to infectious injury, have been linked decrease in bacteria diversity mild severe pathological conditions. Although some progress has made the field, possibilities/procedures restoring skin microbiome are still far from ideal. objective study was design evaluate dissolvable poly(vinyl alcohol)/polyvinylpyrrolidone microneedle (MN) patch containing live Bacillus subtilis. According plan, were distributed equally throughout without compromising morphology mechanical properties needles. B. subtilis successfully released MNs, reaching logarithmic growth phase after 5 h. These MNs demonstrated remarkable antibacterial activity Gram-positive pathogenic S. pyogenes, aureus, C. acnes, while empty control showed no such activity. Finally, mice inserted with single MN loaded GFP-B. presented significantly higher total radiance efficiency (TRE) values compared empty-MN entire experiment. This concept incorporating live, secreting within supportive shows great promise as bacterial delivery system, offering potential shift conventional pharmacological approaches more sustainable symbiotic therapies.

Abstract The development of biomaterials capable on‐demand delivery holds significant promise for wound therapy. Current research is centered on refining design precision and enhancing structural functionality to achieve effective controlled release active agents, thereby facilitating healing. In this study, a coaxial microfluidic electrospray technique employed fabricate microcapsules comprising black phosphorus (BP)‐laden alginate shell gelatin methacrylate (GelMA) core. Curcumin nanoparticles (CNPs) vascular endothelial growth factor (VEGF) are respectively incorporated into the core microcapsules. photothermal performance contributed superior sterilization efficacy in early stages healing, while factors provided robust angiogenic effects during later stages. These attributes enabled significantly accelerate enhance collagen deposition, modulate inflammatory responses rat model, underscoring their potential clinical application.

Wound healing has been a continuous critical focus in clinical practice, posing the ongoing challenges and burdens to patients. Current attempts tend develop multi-drug loaded patches with spatial design. Herein, we present multifunctional microneedle patch that integrates different drugs into separated regions for wound treatment. The is composed of silk fibroin-methacryloyl (SilMA) as base, silver nanoparticles (AgNPs) gelatin methacryloyl (GelMA) tips vascular endothelial growth factor (VEGF). backing endowed antimicrobial properties by AgNPs act an barrier against bacterium invasion. In addition, encapsulated VEGF can effectively promote cell proliferation angiogenesis, which favorable repair. Based on these characteristics, such integrated system significantly prevented bacterial infection promoted vivo. Therefore, it conceived find more practical values other fields.
