Eutectozymes as Soft Hybrid Materials for Advanced Biocatalysis
Advanced Materials, EarlyView.Eutectozymes are sustainable hybrid materials that embed a GOx–HRP cascade within hydrophobic eutectogels featuring a dual supramolecular–covalent network. This architecture preserves native enzyme structure and stability, enables efficient heterogeneous biocatalysis in aqueous media, and positions eutectogels as robust platforms for next‐generation ...

Rethinking Extracellular Vesicle Signaling
Advanced Materials, EarlyView.Extracellular vesicles enable cell communication beyond intracellular cargo delivery. This perspective highlights two plausible surface‐based signaling modes: “bind‐and‐stay” and “bind‐and‐leave.” Transient binding to multiple cells challenges the one‐vesicle‐one‐cell model.
