From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

The Floor‐Ceiling‐Chip, or 2 × 2D = Pseudo‐3D—Approaching 3D Cell Morphology and Organization between Two Opposing 2D Substrates with Cell‐Adhesive Protein Micropatterns

Advanced Healthcare Materials, EarlyView.
Here, we present a novel 3D cell patterning and culture platform. The “Floor‐Ceiling‐Chip” (FC‐Chip) consists of two opposing track‐etched membranes, creating a pseudo‐3D microenvironment for the cells in between. By providing the membranes with micropatterned cell‐adhesive islands of varying geometries and sizes, the FC‐Chip enables control over cell ...

Structurally Constrained Stibenium: Metallomimetic C−Si Bond Activation

Angewandte Chemie, EarlyView.
A structurally constrained stibenium cation supported by a 2,6‐bis(o‐carborano)pyridine pincer‐type ligand was prepared, and its preliminary reactivity toward silanes was investigated. Remarkably, Si−C bonds in silanes undergo activation via an oxidative‐addition‐type process at the cationic Sb center.

Electrochemically Engineered PEDOT:PSS/MXene Composite Electrode for the Label‐Free Procalcitonin Detection

Advanced Materials Interfaces, EarlyView.
Procalcitonin is a key biomarker for bacterial infections, but conventional detection methods are often time‐consuming. Here, we present an electrochemical sensor based on highly conductive Ti3C2Tx MXene combined with PEDOT:PSS, enabling direct antibody immobilization, while a bovine serum albumin coating provides antifouling protection.

Circularly Polarized Luminescent and Melt‐Processable Copper(I)‐Organic Glasses Based on 2,2′‐Bis(diphenylphosphino)‐1,1′‐binaphthyl

Angewandte Chemie, EarlyView.
Homochiral Cu(I) cyanide complexes based on 2,2’‐bis(diphenylphosphino)‐1,1’‐binaphthyl (BINAP) form melt‐quenched and desolvation‐derived metal–organic glasses that exhibit circularly polarized thermally activated delayed fluorescence (TADF) at room temperature, enabling processable chiroptical materials.
