Lab‐in‐a‐Tube System Integrating Hierarchically Wrinkled Electrodes and DNAzyme‐Functionalized Beads for Diagnosis of Clostridioides difficile Infection

Advanced Materials, EarlyView.
The point‐of‐care diagnosis of Clostridioides difficile infection remains challenging due to reliance on slow culture and amplification‐based methods. A lab‐in‐a‐tube electrochemical biosensor integrating DNAzymes, antifouling magnetic beads, and a hierarchically structured flow cell enables amplification‐ and culture‐free detection directly in stool ...

Engineering Immunoregenerative Therapy via an Immunomodulatory Binary Pharmacology Hydrogel Depot for Prolonged Allograft Survival

Advanced Science, EarlyView.
An immunomodulatory hydrogel (iGEL) forms spontaneously upon subcutaneous injection, acting as a tissue‐adhesive depot. It releases anti‐rejection and regenerative agents in response to inflammation, suppressing T‐cell activity, promoting vascular repair, and restoring allograft function without systemic immunosuppression.
