This study systematically investigates how key geometric parameters (including points per inch (PPI), braiding angle, wire count, wire coverage coefficient (WCC), diameter, and braiding architecture), influence the compressive, bending, and torsional behavior of nitinol stents. A combined experimental and finite element analysis (FEA) approach was used to evaluate 54 configurations under three mechanical loading conditions. Results reveal strong linear correlations (R 2 ≥ 0.90) between mechanical performance and PPI, WCC, braiding angle, and diameter. Wire count plays a contradictory role in mechanical performance: higher wire numbers increase bending and torsional stiffness but reduce radial strength. The 1-1 braid structure provides superior torsional and bending strength compared to the 1-2 structure, without compromising compressive strength. Notably, in small-diameter (1 mm) catheters, increasing PPI reduces flexibility and torsional stiffness, contrary to trends observed in larger diameters. These findings offer a comprehensive design guideline for tailoring stent architecture to match specific mechanical and clinical requirements.

Despite its clinical establishment in tumor ablation and hemostasis, conventional MW interventions are largely constrained by non-selective macroscopic heating, leaving the intricate potential of non-thermal biophysical modulation underutilized. The integration of engineered biomaterials provides a transformative framework to bridge this gap, enabling the precise modulation of MW-tissue interactions at the micro-and nanoscale. This review systematically elucidates how rational material design via tuning dielectric and magnetic loss, band-gap engineering, and structural polarization expands MW medicine beyond bulk heating toward controlled biological regulation. We discuss mechanisms where biomaterials function as localized energy antennas to sharpen thermal gradients, as MW-dynamic sensitizers to induce reactive oxygen species generation, and as intelligent interfaces to regulate ionic homeostasis. Representative advancements are summarized across antitumor, antibacterial, and anti-inflammatory therapies, alongside innovations in high-fidelity thermoacoustic imaging. Furthermore, emerging frontiers in non-destructive tissue repair and neuromodulation are highlighted. This review critically examines the design principles and translational challenges of MW-based medical technologies by analyzing correlations between physicochemical parameters and specific biological outcomes. It is expected to advance MW medicine from empirically guided thermal interventions toward mechanism-driven, precision-targeted electromagnetic therapeutics.

Here, we review recent advances that have transformed this concept into a promising therapeutic platform, summarizing progress in mRNA design, delivery technologies, and preclinical and clinical applications across metabolic, oncological, and cardiovascular disorders. We also examine persistent challenges, including achieving precise tissue targeting, extending expression duration, and balancing immune tolerance with translation efficiency, that define the next frontier for clinical translation. By systematically analyzing these obstacles and evaluating emerging solutions, such as next-generation mRNA architectures, targeted biomaterial platforms, and programmable expression control, the review proposes new conceptual and technological directions for the next phase of mRNA therapeutic development. Collectively, these insights provide a structure for advancing mRNA protein replacement from proof-of-concept studies toward a broadly applicable platform for precision medicine.

Rather than eliminating TAMs, emerging strategies aim to functionally reprogram them toward an antitumor phenotype, a therapeutic objective uniquely enabled by the precise, transient, and non-integrating nature of mRNA, which allows reversible modulation without genomic risk. Recent progress in nanocarrier design has improved selective delivery to TAMs through both passive uptake and active targeting, with administration routes tailored to tumor location. Precise immunomodulatory interventions in macrophages, accomplished by mRNA payloads designed to induce pro-inflammatory polarization, enhance phagocytosis, or block immunosuppressive signals, thereby remodel the tumor immune microenvironment and generate synergy with established treatments. Future efforts might concentrate on macrophage heterogeneity, carrier immunogenicity, and scalable formulation development to advance clinical translation, not only in cancer but also in other diseases shaped by dysregulated macrophage function.

TcEVs possess advantages such as high yield, favorable biocompatibility, low immunogenicity, and excellent solid tumor penetration, showing great potential in cancer immunotherapy. However, natural TcEVs exhibit weak targeting ability, limited immune activity, and low drug-loading capacity. To address these issues, several engineering strategies have been adopted to modify the vesicles through genetic engineering, surface modification, and drug-loading, thereby achieving effective treatment of both hematological and solid tumors. This review summarizes TcEVs' classification, biological functions, engineering strategies, and applications in cancer immunotherapy, while discussing challenges and prospects to facilitate their clinical translation.

However, achieving consistent and effective healing remains a clinical challenge, especially in chronic or complex wounds. ADSC-derived exosomes (ADSC-Exos) have emerged as a key cell-free alternative, functioning as nanoscale messengers that transfer bioactive molecules to coordinate tissue regeneration. Unlike cell-based therapies, ADSC-Exos offer enhanced safety, stability, and logistical advantages while retaining potent regulatory capacity. They orchestrate multiple stages of wound healing by promoting angiogenesis, modulating inflammation, and accelerating re-epithelialization. This review first evaluates the relative benefits and limitations of various mesenchymal stem cells-derived cell populations for wound therapy. We then systematically examine the molecular mechanisms and functional roles of ADSC-Exos in skin repair, highlighting recent advances in their isolation, engineering, and delivery. Furthermore, we discuss current challenges and strategic insights for clinical translation. By integrating existing evidence with future perspectives, this review aims to guide the development of ADSC-Exos-based acellular therapies toward improved wound regeneration outcomes.

While autologous nerve grafting serves as the current gold standard treatment, its limitations include donor site morbidity and limited donor nerve availability. As a promising alternative, nerve guidance conduits (NGCs) have emerged within the field of tissue engineering. Incorporating electrical stimulation into NGCs has been shown to facilitate peripheral nerve repair by promoting Schwann cell migration and neurite extension. A significant advancement in this area is the application of piezoelectric biomaterials, which generate endogenous electrical signals from physiological mechanical stimuli. This self-powered mechanism eliminates the need for external power sources or additional surgical interventions. This review systematically examines the material design, fabrication strategies, and electromechanical properties of piezoelectric NGCs, along with their recent applications for enhancing Schwann cell function, guiding axonal growth, and promoting functional nerve recovery. Furthermore, it discusses current challenges and future directions, aiming to provide novel insights for the development of next-generation intelligent neural repair materials.
