ABSTRACT In recent years, with the rapid development of flexible electronics, implantable electronic devices have received increasing attention, and they provide new solutions for medical diagnosis treatment. To ensure long‐term stable operation in internal environment, materials conductivity, flexibility, biocompatibility, other properties are high demand. Hydrogels polymers three‐dimensional network structures that not only physical chemical similar to those biological tissues but can be also modulated by introducing functional groups regulate adhesion, self‐healing, functions. Therefore, hydrogel‐based bioelectronic considered a candidate direction future biomedical field. Here, this paper reviews research progress molecular design performance modulation functionalized hydrogels based on four key hydrogels: toughness. The latest use device applications is summarized below. Finally, discussions given challenges opportunities devices.

Iron-based metal-organic frameworks (Fe-MOFs) are widely used for agricultural chemical delivery due to their high loading capacity, and they also have the potential provide essential iron plant growth. Therefore, hold significant promise applications. Evaluating biotoxicity of Fe-MOFs is crucial optimizing use in agriculture. In this study, we natural biomacromolecule carboxymethyl cellulose (CMC) encapsulate Fe-MOF NH2-MIL-101 (Fe) (MIL). Through hydroponic experiments, investigated biotoxic effects on rice before after CMC modification. The results show that accumulation dependent dose exposure concentration Fe-MOFs. modification (MIL@CMC) can reduce release rate Fe ions from aqueous solutions with different pH values (5 7). Furthermore, MIL@CMC treatment significantly increases absorption by both aboveground root parts rice. alleviated growth inhibition seedlings increased biomass under medium- high-exposure conditions. Specifically, roots, MIL induced a more intense oxidative stress response, activities related antioxidant enzymes (CAT, POD, SOD) MDA content. Our demonstrated encapsulation NH2-MIL-101(Fe) using effectively damage promoted uptake These findings suggest rational positive effect reducing phytotoxicity MOFs improving biosafety
