Advanced Science, EarlyView.We report a robust aerogel digital biosensor by integrating an enzyme‐mediated amorphous MOF within an aerogel matrix for on‐site pesticide detection. The enzyme‐mediated assembly strategy enables in situ tailoring of MOF into a porous amorphous structure, achieving both high stability and activity.

Advanced Science, EarlyView.We report photostable, photoluminescent deep eutectic solvents (DESs) powered by in situ‐formed zero‐dimensional (0D) halometallates. Stabilized by microenvironment‐controlling hydrogen bond acceptor (HBA) and donor (HBD) networks, these DESs exhibit vibrant, metal ion‐tunable emission (PLQY = 60.2%).

Advanced Science, EarlyView.Water‐induced quenching challenges organic RTP materials, but a counter‐intuitive strategy employs HOF to encapsulate carbonyl guests, where water functions as a structural reinforcer. This achieves water‐enhanced ultralong RTP with full‐color emission (blue to deep red), overcoming intracellular quenching for high‐signal cellular imaging, alongside 4D

All‐Solution‐Processed Perovskite Light‐Emitting Transistors Enabled by a Fully Organic Architecture
Advanced Electronic Materials, EarlyView.Fully solution‐processed light‐emitting transistors based on CsPbBr3 perovskite nanocrystals (Pe‐LETs) are demonstrated using an all‐organic platform. By optimizing film formation and device integration, the Pe‐LETs achieve bright green emission with excellent color purity and a peak external quantum efficiency of 4.17 × 10−3 %, marking a step forward ...

Optimization of CEST MRI Reporter Protein Design Using Cation‐Pi Networks
Chemistry – A European Journal, EarlyView.A novel engineering approach can produce reporter proteins for cell and viral therapy tracking with unique magnetic resonance imaging (MRI) signatures, detectable with chemical exchange saturation transfer (CEST). We discover how cation‐π interactions between amino acid groups can help us fine‐tune magnetic resonance properties for noninvasive ...
