“…Since the discovery of MOFs in late 1990, MOF and MOF-based functional materials have emerged and been widely applied in diverse application fields. [129][130][131][132] The versatility of metal nodes and the connections in all possible directions endow MOFs with structural diversity and extensive physical and chemical properties. [131,133,134] With the development of synthetic methods and surface modification engineering, three efficient synthetic strategies (rapid nucleation, nanoreactor confinement, and coordination modulation) and two approaches for surface functionalization of MOF (covalent external surface and coordinative external surface) were used for designing MOF.…”

The extensive research into developing new nanomedicines during the past few years has witnessed significant progress in diverse biomedical fields, especially for combating drug resistance in antitumor and antibacterial therapies. Recently, transition-metal-based enzymatic nanoagents (TM-EnzNAs) with catalytic production of reactive oxygen species (ROS) have been designed and intensively explored, which have become powerful nanoplatforms and exciting research frontiers in constructing next-generation nanotherapeutics to combat drug-resistant tumors and bacteria. Here, the focus is on the recent design, fundamental principles, and material chemistries in developing and applications of TM-EnzNAs. At first, the different ROS-producing mechanisms and the key factors to enhance ROS level are carefully concluded, and the analytic methods are systematically summarized. Then, the rationally engineered TM-EnzNAs via different synthetic approaches with high ROS producing efficiencies are comprehensively discussed, especially the catalytic activities, mechanisms, and structure-function relationships. After that, the representative applications of these ROS-catalytic TM-EnzNAs for antitumor and bacterial eradication are summarized in detail. Finally, the primary challenges and future perspectives have also been outlined. It is anticipated new therapeutic insights into combating drug-resistant tumors and bacteria will be provided, and significant new inspiration for designing future enzymatic nanoagents is offered.

Herein, a dual‐band tunable ideal absorber based on graphene array, and the dynamic tuning performance of the perfect absorber in the terahertz band and its sensing properties based on graphene metamaterials are studied. The absorber shows two perfect absorption peaks at 1.01 and 1.86 THz, with an absorbance of 99.5% and 99.9%, respectively. With an elevation angle in the range of 0°–30° and a frequency in the range of 0.971–1.100 THz or 1.794–1.897 THz, the absorber designed herein can achieve an absorbance greater than 90%. Owing to the superior properties of graphene, dynamic tuning of the absorption frequency band, absorption bandwidth, and relative bandwidth of the absorber can be achieved by adjusting the Fermi level of graphene. In addition, adjusting the relaxation time realizes dynamic tuning of the absorption bandwidth and the absorbance with constant resonant frequency and fixed geometric parameters. Moreover, the sensitivity of the absorber reaches 492.5 GHz/RIU, which can achieve the sensing resolution required for the resonance frequency. This research provides a new concept for the development of high‐performance terahertz devices.

challenge to clearly and rapidly indicate the temperature variation. [21][22][23][24] To remind people to avoid the scald faster, it is desired to discover a simple way to indicate the temperature of the heater textiles under the voltage. [25][26][27][28] The changes in environmental conditions can be observed visually by the object's color. [29][30][31] Smart color-changing textiles include electrochromic textiles, photochromic textiles, humidity discoloration textiles, and thermochromic textiles. [32][33][34][35][36][37] The ambient temperature can be indicated by the color change of thermochromic textiles, providing the temperature indication for the user. [38,39] On account of the comfortable capability, deformability, and high flexibility, thermochromic textiles have potential applications in home decoration, information display, and temperature sensors. [40][41][42][43][44][45][46][47][48][49] Thermochromic textiles can certainly provide intelligent services in addition to the protective nature and fashion of fabric. [50][51][52] To realize the temperature indication of electrothermal textiles, the thermochromic dyes have been integrated with the conductive materials based on Joule's law. Xu's team fabricated a core-sheath nanocomposite yarn, which retains the intrinsic properties of the fabric and benefits its applications as wearable electronics for achieving electro-thermochromic textiles with durable electro-thermochromic performance. [44] Moreover, the response relationship between the applied voltage and the temperature of conductive fabric has been explored based on Joule's law in our previous work. [51] Although these electrothermal textiles show the obvious electrical-triggered reversible color-changing property, surprisingly, little attention has been devoted to the fabrication of electrothermal textiles that can detect their temperature in real time for avoiding burns to the human body.To solve this problem, we fabricate a Joule heating fabric with superior resistance heating properties and gradient response discoloration via coating. The graphene paste as a heat source, titanium white paste, and gradient response thermochromic paste for indicating the temperature generated by the Joule heating are coated layer by layer on the cotton fabric surface. Especially, the titanium white layer not only covers the graphene to reduce its influence on the color of the Joule heating fabric but also ensures the optical contrast of the Joule heating fabric. The Joule heating fabric exhibits favorable color-changing Smart heating textiles with high safety factors are urgently demanded when multitudinous intelligent heater products spring up in wearable electronics. We report a Joule heating fabric with gradient response discoloration for visual temperature detection. The Joule heating fabric exhibits high electrical conductivity, and the surface resistance is around 150 Ω (2 cm). The temperature of Joule heating fabric rapidly rises from room temperature (25.6 °C) to 42.6 °C at 8 V in 160 s and keeps an equilib...
