A Bone Marrow–Mimetic Hydrogel Enables Dual‐Phase Hemostasis and Vascularized Osteogenesis for Cranial Defects

Advanced Science, EarlyView.
A biomimetic, fiber‐reinforced hydrogel (FE‐PDA@Fib/Gel‐TG) that enables dual‐phase cranial defect repair. The system provides: instant hemostasis in the early stage, and sustained co‐delivery of pro‐angiogenic and osteogenic signals for synergistic vascularized bone regeneration.

Bandgap‐Engineered PtxTey:Ag2Te Composite Quantum Dots Enable Programmable NIR‐II Imaging and Photothermal‐Immune Synergistic Therapy

Advanced Science, EarlyView.
A bandgap‐engineered PtxTey:Ag2Te quantum dot platform enables tunable NIR‐IIb emission for deep‐tissue imaging and mild photothermal therapy. Conjugation with αPD‐L1 confers dual tumor targeting and real‐time monitoring of PD‐L1 dynamics. Mild photothermal modulation induces immune reprogramming, enhancing checkpoint blockade efficacy and achieving ...

NIR‐II‐Trackable LYTACs Phyto‐Nanotheranostics for Source‐Microenvironment Dual‐Track ROS Regulation in Acute Gouty Arthritis

Advanced Science, EarlyView.
The TPR‐LYTACs nanomaterial offers a dual‐pathway strategy for precise gouty arthritis treatment by targeting and degrading the ROS‐producing enzyme NOX2 inside macrophages while its antioxidant core clears accumulated ROS outside. This “source inhibition and microenvironment scavenging” approach, guided by NIR‐II imaging, effectively controls local ...
