Summary: A novel cellulose nanofibrils modified hydrogel composite was synthesized for simultaneous adsorption and detection of antibiotics in water resources. The composite showed remarkable adsorption capacity and maintained its initial adsorption capacity even after consecutive adsorption/desorption cycles. The composite also exhibited blue fluorescence, enabling selective and efficient detection of antibiotics.

Summary: The injectable self-healing polysaccharide hydrogel was prepared by forming Schiff base bonds between aldehyde-modified methylcellulose and carboxymethyl chitosan. Copper sulfide nanoparticles and pH-sensitive doxorubicin-loaded zeolitic imidazolate frameworks nanoparticles were dispersed in the hydrogel system. This hydrogel system achieved synergistic photothermal-photodynamic-chemo therapy for tumors and provided inspiration for constructing a platform combining hydrogel and multifunctional nanomaterials for effective multimodal tumor therapy.

Summary: This study reveals the significant impacts of ZIFs on algae, showing that the effects are reversible. Different types of ZIFs (such as ZIF-8 and ZIF-67) induce toxicity effects and are internalized differently, while factors related to oxidative phosphorylation are crucial for the persistence of plant toxicity.

Summary: Due to antibiotic misuse and the increase in drug-resistant bacteria, it is crucial to develop new antibacterial strategies for treating infected wounds. In this study, stable tricomplex molecules (PA@Fe) were synthesized by combining protocatechualdehyde (PA) and ferric iron (Fe), and embedded in a gelatin matrix to create Gel-PA@Fe hydrogels. The embedded PA@Fe acted as a crosslinker, improving the mechanical, adhesive, and antioxidant properties of the hydrogels through coordination and dynamic Schiff base bonds. It also functioned as a photothermal agent, effectively killing bacteria by converting near-infrared (NIR) light into heat. In vivo evaluation using an infected full-thickness skin wound mice model demonstrated that Gel-PA@Fe hydrogels promoted collagen deposition and accelerated wound closure, indicating their potential in enhancing the healing process of infected wounds.

Summary: ZIF-8-PhIm was prepared for the removal of p-nitrophenol from petrochemical wastewater. It exhibited stronger interactions, a multistage pore structure, increased hydrophilicity, and higher adsorption capacity compared to ZIF-8 materials. The adsorption process was described by the Langmuir isotherm and pseudo-second-order kinetic models, and hydrogen bonding and p-p interactions played a dominant role.

Summary: This study evaluated the colloidal stability and structural integrity of copper-doped ZIF-8 nanoparticles in water and blood serum. The findings showed that the structural integrity of colloidal copper-doped ZIF-8 can be maintained in blood serum for several days, making it a potential candidate for biomedical applications in treating atherosclerosis. The study also confirmed the ability of copper-doped ZIF-8 nanoparticles to convert blood borne s-nitrosothiols into nitric oxide, and the conversion was more sustained compared to free copper ions in solution.
