Near‐Infrared Switch‐Driven Macrophage Dynamically Reprogramming for Anti‐Infection and Tissue Healing on Polyetheretherketone Implants

open access: yesAdvanced Science, EarlyView.
This study develops a Mg‐H‐SPEEK implant with NIR‐switchable immunomodulatory properties. Under NIR, it promotes M1 macrophages for antibacterial action; without NIR, it induces M2 reprogramming to enhance tissue healing. This dual‐function material offers a smart strategy for reducing infection and improving integration in percutaneous implants ...

Pulmonary‐Targeted Nanoparticles Interrupt the Malignant Mechanical and Biochemical Signaling Crosstalk for Idiopathic Pulmonary Fibrosis Therapy

open access: yesAdvanced Science, EarlyView.
Idiopathic pulmonary fibrosis (IPF) progression is driven by TGF‐β induced biochemical signals and mechanical signals from increased ECM stiffness. Pulmonary‐targeted VB‐RT NPs not only eliminate excessive ROS and penetrate the dense ECM collagen barrier via NO release, but also simultaneously interrupt the persistent malignant between mechanical and ...

Trimetallic Nanozyme‐Embedded Smart Hydrogel Enables NIR‐Controlled Bacterial Killing and Oxidative Stress Alleviation

open access: yesAdvanced Science, EarlyView.
A microenvironment‐responsive hydrogel is developed incorporating polymyxin B‐modified AuMnCu nanozymes and dual drugs (tannic acid and tobramycin). At infection sites, it generates ROS, releases drugs responsively, and enhances mild photothermal action to disrupt bacterial redox balance.

Immunomodulatory Hydrogel Coating with SeNPs and Lithium Silicate Synergistically Promotes Osseointegration and Prevents Infection on Titanium Implants

open access: yesAdvanced Science, EarlyView.
This study introduces a multifunctional hydrogel coating (Lap‐CMCSMA/GelMA@SeNPs) that scavenges ROS, modulates immune responses, and shows strong antibacterial activity. It effectively restores the peri‐implant microenvironment. The coating exhibits excellent biocompatibility and promotes osteogenic differentiation.
