Microwave (MW) medicine has emerged as a distinct interdisciplinary field, predicated on the unique capacity of non-ionizing electromagnetic radiation to penetrate deep-seated tissues and interact efficiently with biological dielectrics for diverse therapeutic and diagnostic applications. 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.

Messenger RNA (mRNA) protein replacement therapy harnesses synthetic mRNA to direct endogenous protein synthesis, offering a versatile approach to restore or substitute proteins that are absent or dysfunctional in disease. 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.

Tumor-associated macrophages (TAMs) are pivotal regulators of the immunosuppressive tumor microenvironment and major contributors to resistance against conventional and immunotherapeutic interventions. 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.

Magnesium alloys are primarily composed of magnesium, with the additions of elements such as calcium, yttrium, and zinc. In the human physiological environment, they gradually degrade, and their degradation products can be absorbed, exhibiting excellent biocompatibility, mechanical properties comparable to bone tissue, and degradability; thus, they hold broad prospects in orthopedics. Nanotechnology involves the design and manufacture of materials, devices, and systems with unique physical, chemical, and biological properties by controlling the arrangement and interactions of atoms, molecules, or nanostructural units at the nanoscale (1-100 nm). The integration of these two technologies shows exceptional potential for orthopedic regenerative repair. Nanotechnology significantly enhances the mechanical performance, bioactivity, antibacterial properties, and controlled degradation of biodegradable magnesium alloys through various approaches, while biodegradable magnesium alloys provide an ideal biomaterial carrier for nanotechnology, enabling the better exertion of its advantages in bone tissue repair. This review summarizes the innovations arising from the fusion of magnesium alloys and nanotechnology in bone repair, aiming to advance the evolution of orthopedic medical devices, promote a shift in clinical treatment paradigms toward personalized and precise therapy, and ultimately deliver superior and more efficient therapeutic options for patients with orthopedic conditions, thereby improving human health and quality of life.

As the primary skin-contact interface in wearable electrocardiograph (ECG) devices, epidermal electrodes play a pivotal role in determining both signal quality and biocompatibility. With continuous advancements in materials science and structural engineering, next-generation flexible and stretchable bioelectrodes have emerged, enabling long-term ECG monitoring and offering superior signal-to-noise ratios compared to conventional clinical electrodes. Their performance in ensuring reliable signal acquisition and user comfort is primarily governed by key interfacial mechanical and electrical properties, including mechanical compliance (i.e., flexibility and stretchability), interfacial adhesion (i.e., conformability and adhesion strength), and electrical characteristics (i.e., contact impedance). In recent years, significant progress has been made in enhancing the signal acquisition capabilities of flexible and stretchable bioelectrodes by optimizing these critical interfacial attributes. This review highlights the latest advances in conformable epidermal electrodes, encompassing traditional wet electrodes, flexible dry electrodes, novel dry electrodes based on organic electrochemical transistors, and integrated wearable systems. We systematically examine strategies for improving skin-electrode interface performance in ECG monitoring. Finally, we discuss ongoing challenges and future directions to advance epidermal electrode technologies for next-generation wearable healthcare applications.

A large amount of medical equipment is now extensively utilized in healthcare institutions to assist clinical practitioners in the diagnosis and treatment of diseases. And the applications of such advanced and sophisticated medical equipment have greatly improved the quality of patient care, significantly alleviated the sufferings of patients, and facilitated their rehabilitation. Nevertheless, failures and malfunctions of medical equipment have compromised its reliability and effectiveness as well as jeopardizing the safety of patients and clinical staffs. And a majority of the failures can be attributed to the insufficient and inappropriate maintenance. Therefore, it is imperative to implement effective maintenance management to ensure that medical equipment is in its optimal function, and thereby mitigating the clinical risk resulted by adverse events. The presented review mainly discussed the maintenance strategies of medical equipment including corrective maintenance, preventive maintenance and predictive maintenance. In order to replace the fixed-interval of preventive maintenance, we systematically discussed methods to adjust the maintenance period. Additionally, two strategies to predicting future failures of medical equipment through processing and analyzing the maintenance data obtained from the historical maintenance logs and condition data collected by the embedded sensors are elaborated. Besides, the classification and life cycle of medical equipment are also summarized.

Incorporating bioactive molecules, such as growth factors and anti-inflammatory agents, can further enhance the effectiveness of hydrogels. Additionally, stem cells can be loaded into hydrogels to improve tissue regeneration and help modulate the wound microenvironment. Recent advancements in hydrogel technology have also led to the development of smart hydrogels that can respond to changes in wound conditions, such as glucose levels and pH. These intelligent dressings offer personalized care by delivering targeted treatments based on real-time wound data. This review explores the mechanisms behind DFU development, the role of hydrogels in wound healing, and recent progress in hydrogel technologies for personalized DFU care.
