Dynamic Physicochemical Gradients for Tendon–Bone Regeneration

Advanced Functional Materials, EarlyView.
Dynamic physicochemical gradients offer a framework for reconnecting soft tendon and hard bone. This Review examines how hydration, transport, loading and degradation reshape these gradients during healing. Coordinating regional biological cues with progressive transfer of load from scaffold to tissue guides the design of interfaces that retain ...

High‐Modulus Skeleton‐Reinforced PDMS Microstamps for Precision Transfer Printing of Microscale Devices

Advanced Functional Materials, EarlyView.
Elastomeric micropillars bend under contact loading, sliding microscale devices out of alignment during transfer printing. A hybrid PDMS stamp embeds a high‐modulus skeleton within each pillar while retaining a compliant contact surface. The reinforcement confines pillar deformation, suppressing interfacial sliding and preserving array registration on ...

One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

Advanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological
