Engineered Allosteric Biosensor for In Situ DNA Glycosylase Detection in Neuroblastoma Risk Stratification and Drug Resistance Monitoring

Advanced Science, EarlyView.
An engineered allosteric biosensor (UUU‐DZ‐tFNA) was developed, in which UDG specifically recognizes and activates a DNAzyme to achieve signal cycle amplification in a sequentially activatable mode. UUU‐DZ‐tFNA achieves in situ UDG detection across multiple biological levels and facilitates risk stratification and drug resistance monitoring of NB ...

Hydrogel Phase Transition‐Driven Soft Gating Circumvents Debye Screening for Advanced Biosensing

Advanced Science, EarlyView.
A 3D soft gate utilizes a macroscopic hydrogel phase transition to effectively circumvent Debye screening in high‐salt environments. The intact matrix maximizes transmembrane ion flux via volumetric Donnan enrichment and superhydrophilicity. Target‐triggered network disassembly abolishes these effects, introducing a synergistic physical barrier.

The Cytoplasmic MicroRNA‐Production Complex Regulates MicroRNA Sorting to Extracellular Vesicles During Synaptogenesis

Advanced Science, EarlyView.
The mechanisms of microRNA cargo sorting to extracellular vesicles, important mediators of cell communication, are not fully understood. This study reveals that the microRNA‐production machinery acts as a ‘hub’ for the sorting of microRNAs to extracellular vesicles, a process regulated by dynamic organelle interactions.

Stabilizing Functional Nucleic Acids for Real‐Sample Diagnostics

Angewandte Chemie, EarlyView.
Functional nucleic acids enable programmable real‐sample diagnostics, but often lose function in complex biological matrices. This review highlights four stabilization levers—chemical, topological, architectural, and microenvironment/interface engineering—that preserve aptamer and DNAzyme performance in saliva, serum, urine, and stool, reframing ...
