Injectable Chondroitin Sulfate Methacrylate Hydrogel Microspheres Co‐Loaded with GLPM Nanozyme, Dexamethasone, and Stem Cells for Synergistic Osteoarthritis Therapy

Advanced Science, EarlyView.
A multifunctional injectable microsphere system is fabricated via UV‐assisted microfluidic cross‐linking, integrating nanozyme‐based ROS scavenging, sustained dexamethasone release, and stem cell delivery. Upon IA injection, the microspheres adapt to joint stress, suppress inflammation, and promote cartilage regeneration, offering a minimally invasive ...

The Dynamic Energy Band Model of Contact‐Separation and Sliding Mode Triboelectric Charging of Polymers at the Metal‐Polymer Interface

Advanced Science, EarlyView.
Triboelectric charge generation at polymer‐metal interfaces arises from the interplay of intra‐ and inter transformation reactions of mechanochemically generated species, physical properties of polymers, environmental conditions. The direction and the magnitude of electron transfer between metal and polymer are dynamically governed by the relative ...

A Strain Decoupling Packaging Strategy for High‐Fidelity Ultrathin Silicon Shape Sensors for Soft Medical Robotics

Advanced Science, EarlyView.
Reliable soft sensors are essential for precise control in soft medical robots such as endoscopes. We developed ultrathin silicon piezoresistive sensors and their oil‐lubricated slidable packaging, which enables high‐fidelity shape sensing of silicon gauges by mechanically isolating the sensing element within a dual‐layer film.

Multimodal Layer‐Crossing Interrogation of Brain Circuits Enabled by Microfluidic Axialtrodes

Advanced Science, EarlyView.
The study introduces a flexible microfluidic axialtrode that integrates optical, electrical, and chemical modalities within a single polymer fiber. By redistributing electrodes and fluidic channels along the fiber axis via angled cleaving, it enables simultaneous optogenetic stimulation, electrophysiological recording, and drug delivery across brain ...

A Shear Thickening Colloidal Suspension Functioning via Progressive Impact Jamming with Persistent Lubrication Layer

Advanced Science, EarlyView.
An ionic liquid‐based shear‐thickening fluid (ILSTF) exhibits lubricated dynamics from strong shear thickening to impact‐triggered jamming. A persistent nanometric solvation layer around silica governs both the shear thickening saturation in rheology and jamming front propagation under dynamic impact compression.
