“…TEM testing indicated that the prepared EG@AgNPs were uniformly spherical particles with 3.55 nm of average particle size (Figure S3a), which is consistent with the results of AgNPs with antibacterial effects reported in the literature. In addition, the DLS test results show that the percent deviation index (PDI) and Zeta potential of EG@AgNPs were 0.256 and −18.7 mV, respectively, indicating that the prepared AgNPs are well-dispersed and remain stably suspended within the EG solution …”

“…38−40 The DLS test revealed a polydispersity index of 0.369 and a surface Zeta potential of −20.4 mV for OSA-CQDs (Figure S2b), indicating the considerable dispersion and stability of the prepared OSA-CQDs, with a negatively charged surface. 41 The conductivity of the OSA-CQDs solution was conclusively measured to be 0.51 S/m by using a portable conductivity meter. Next, employing it as a liquid wire successfully illuminated an LED lamp (Figure S2c), further demonstrating its conductivity.…”

Conductive hydrogels are ideal materials for intelligent medical devices, human-machine interfaces, and flexible bioelectrodes due to their adjustable mechanical properties and electrical responsiveness, whereas it is still a great challenge to achieve the integration of excellent flexibility and biocompatibility into one hydrogel sensor while also incorporating self-healing, selfadhesion, environmental tolerance, and antimicrobial properties. Here, a nanocomposite conductive organohydrogel was constructed by using collagen (Col), alginate-derived carbon quantum dots (OSA-CQDs), poly(acrylic acid) (PAA), ethylene glycol reduced AgNPs, and Fe 3+ ions. Depending on OSA-CQDs with multiple chemical binding sites and high specific surface area as cross-linkers, while coupling highly biologically active Col chains and PAA chains are serving as an energy dissipation module, the resulting organohydrogel exhibited excellent flexibility (795% of strain, 193 kPa of strength), high cell compatibility (>95% survival rate), self-healing efficiency (HE = 79.5%), antifreezing (−20 °C), moisturizing (>120 h), repeatable adhesion (strength >20 kPa, times >10), inhibitory activity against Escherichia coli and Staphylococcus aureus (9 and 21.5 cm 2 ), conductivity, and strain sensitivity (σ = 1.34 S/m, gauge factor (GF) = 11.63). Based on the all-in-one integration of multifunction, the organohydrogel can collaboratively adapt to the multimode of strain sensing and electrophysiological sensing to realize wireless real-time monitoring of human activities and physiological health. Therefore, this work provides a new and common platform for the design and sensing of next-generation hydrogel-based smart wearable sensors.

Covalent organic frameworks (COFs) stand for a class of emerging crystalline porous organic materials, which are ingeniously constructed with organic units through strong covalent bonds. Their excellent design capabilities, and uniform and tunable pore structure make them potential materials for various applications. With the continuous development of synthesis technique and nanoscience, COFs have been successfully combined with a variety of functional materials to form COFs‐based composites with superior performance than individual components. This paper offers an overview of the development of different types of COFs‐based composites reported so far, with particular focus on the applications of COFs‐based composites. Moreover, the challenges and future development prospects of COFs‐based composites are presented. We anticipate that the review will provide some inspiration for the further development of COFs‐based composites.

“…Glucose is a kind of polyhydroxy aldehyde, which is one of the most widely distributed and important monosaccharides in nature . Glucose is not only the main energy source of the human body, but also one of the main components of most foods. , In the human body, the imbalance of glucose in the blood will lead to a series of diseases, such as diabetes, hypoglycemia, decreased glucose tolerance, and decreased fasting blood sugar, posing a great threat to human life. , In the food industry, testing the glucose content of foods and beverages can not only control glucose intake, but also further monitor blood sugar levels . In addition, the detection of glucose also helps to monitor and control the content of additives in food, thus ensuring the safety and quality of food .…”

High-entropy alloys have long been used as a new type of alloy material and have attracted widespread concern because of their excellent performance, including their stable microstructure and particular catalytic properties. To design a safer preparation method, we report a novel approach targeting green synthesis, using tea polyphenols to prepare PtPdNiFeCu high-entropy alloy nanoparticles for glucose detection. The fabricated sensors were characterized by transmission electron microscopy and electrochemical experiments. Physical characterization showed that the nanoparticle has better dispersibility, and the average particle size is 7.5 nm. The electrochemical results showed that Tp-PtPdNiFeCu HEA-NPs had a high sensitivity of 1.264 μA mM –1 cm –2 , a low detection limit of 4.503 μM, and a wide detection range of 0 - 10 mM. In addition, the sensor has better stability and selectivity for glucose detection.
