A Polyoxometalate—Carbon Nanotube Enhanced Electrochemical Sensor for Aptamer‐Based Diagnostics

open access: yesAdvanced Sensor Research, EarlyView.
The high electroactive surface area of multi‐walled carbon nanotubes decorated with aptamer‐functionalized polyoxovanadate units enables a ≈1000‐fold increase in peak current response for a model diclofenac detection in aqueous solution compared to unmodified platinum microelectrodes.

Bio‐Inspired Polymer Nanoreactor: Integrating Hemin Coordination and Micellar Confinement for Catalysis in Water

open access: yesAdvanced Sustainable Systems, EarlyView.
This study develops an amphiphilic copolymer nanocarrier (P(His‐r‐Sty)‐b‐PDMAA) for aqueous hemin catalysis, enabling efficient styrene cyclopropanation (94.4% yield, 0.3 mol% hemin) with excellent recyclability (>90% activity after 4 cycles), overcoming solubility and microenvironment challenges.

Decoding Handwriting Trajectories from Intracortical Brain Signals for Brain‐to‐Text Communication

open access: yesAdvanced Science, EarlyView.
By developing a novel framework that optimizes both shape and temporal loss during decoder training, the authors successfully reconstruct human‐recognizable handwriting trajectories from intracortical neural signals for both Chinese characters and English letters, effectively resolving the temporal misalignment problem in clinical BCIs, thereby ...

Identifying Tipping Points during Healthy Brain Aging through Single‐Nucleus Transcriptomic Analysis

open access: yesAdvanced Science, EarlyView.
This study applies single‐nucleus transcriptomics and systems dynamics to uncover nonlinear aging patterns in healthy human brains. By introducing dynamic network biomarker theory, the authors identify a critical tipping point at ages 56–60 during aging, and highlight glial instability as a key mediator.

Chronically Stable, High‐Resolution Micro‐Electrocorticographic Brain‐Computer Interfaces for Real‐Time Motor Decoding

open access: yesAdvanced Science, EarlyView.
A high‐resolution micro‐electrocorticographic (µECoG) brain‐computer interface (BCI) for real‐time motor decoding is reported. The application of flexible, scalable µECoG electrode arrays overcomes the insufficient spatial resolution in conventional ECoG BCIs.
