Diabetic alveolar bone defect (DABD) causes persistent bacterial infection, prolonged inflammation, and delayed bone healing, making it a considerable clinical challenge. In this study, by integrating silver nanoclusters (AgNCs) and M2 macrophage‐derived extracellular vesicles (M2EVs), a multifunctional DNA‐based hydrogel, called Agevgel, is developed with antibacterial, anti‐inflammatory, immunomodulatory,...
Developing high‐efficiency and stable oxygen evolution reaction (OER) electrocatalysts is an imperative requirement to produce green and clean hydrogen energy. In this work, the FeCoSy/NCDs composite with nitrogen‐doped carbon dots (NCDs) modified Fe–Co sulfide (FeCoSy) nanosheets is prepared by using a facile and mild one‐pot solvothermal method. Benefiting from the low crystallinity and the synergistic...
Stable platforms of host–guest catalysts are indispensable in the field of heterogeneous catalysis, however, clarifying the specific effect of host remains challenging. Herein, polyoxometalate (POM) is encapsulated in three types of UiO‐66(Zr) with different controlled densities of defects by the aperture opening and closing strategy at ambient‐temperature. It is found that catalytic activity of POM...
Surface‐enhanced Raman spectroscopy (SERS) is a promising technology for wearable sensors due to its fingerprint spectrum and high detection sensitivity. However, since SERS‐activity is sensitive to both the distribution of “hotspots” and excitation angle, it is profoundly challenging to develop a wearable SERS sensor with high stability under various deformations during movements. Herein, inspired...
Local tumor photothermal treatment with the near‐infrared light at the second window (NIR‐II) is a promising strategy in triggering the in situ tumor vaccination (ISTV) for cancer therapy. However, limited penetration of photothermal agents within tumors seriously limits their spatial effect in generating sufficient tumor‐associated antigens, a key factor to the success of ISTV. In this study, a nano‐adjuvant...
The diversity by nano/microstructural material or device constructing can provide the exciting opportunity for sensitivity and selectivity to achieve facile and efficient multianalyte recognition for clinical diagnosis, environment monitoring, etc., in complex system analysis. Colloidal poly(styrene–methyl methacrylate–acrylic acid) (poly(St–MMA–AA)) nanoparticle‐assembled photonic crystals (PCs)...
Isolating and in situ profiling the heterogeneous molecular phenotype of circulating tumor cells are of great significance for clinical cancer diagnosis and personalized therapy. Herein, an on‐chip strategy is proposed that combines size‐based microfluidic cell isolation with multiple spectrally orthogonal surface‐enhanced Raman spectroscopy (SERS) analysis for in situ profiling of cell membrane proteins...
