Rewiring Pyroptosis to Potentiate Cancer Immunotherapy via a Gasdermin D Agonist Bypassing Caspase‐3

Advanced Science, EarlyView.
This work introduces a small‐molecule agonist, DIBDO, that bypasses Casp‐3 to directly trigger GSDMD‐mediated pyroptosis in tumors. Activated by glutathione, DIBDO generates singlet oxygen and molecular iodine, blocking Casp‐3 pathways and inducing immunogenic cell death.

A pH‐Switchable Cerium Single‐Atom Enzyme for Peri‐Implantitis Therapy via JAK‐STAT Signaling Axis‐Mediated Macrophage Reprogramming

Advanced Science, EarlyView.
A pH‐switchable cerium single‐atom enzyme is developed for stage‐specific peri‐implantitis therapy. Acidic conditions trigger antibacterial peroxidase‐like activity, whereas neutral conditions activate an antioxidant superoxide dismutase ‐ and catalase ‐like enzymatic relay. This microenvironment‐adaptive catalytic strategy suppresses the IL‐6/JAK‐STAT

Surface States Mediated NIR Two-Photon Fluorescence of Iron Oxides for Nonlinear Optical Microscopy

, 2013
The development of fluorescent iron oxide nanomaterials is highly desired for multimodal molecular imaging. Instead of incorporating fluorescent dyes on the surface of iron oxides, a ligand-assisted synthesis approach is developed to allow near-infrared (

Topology‐Enabled Finite‐Band Absorption Framework Based on a Bioinspired Nested Dual‐Loop Architecture

Advanced Science, EarlyView.
A nuclear‐pore‐inspired nested dual‐loop architecture redistributes electromagnetic energy through coupled transport, confinement, and dissipation pathways. Integrated with Co/Fe3O4 dual‐magnetic composites and topology optimization, the 11‐mm‐thick absorber delivers continuous 2–40 GHz attenuation, raises finite‐band structural utilization to 82%, and

Exploring interfacial magnetism in all-spinel Fe3O4/MgCr2O4/Fe3O4 epitaxial heterostructures.

Nanoscale
Epitaxial heterostructures integrating thin Fe3O4 films hold great potential for spintronics, magnetoionics, and multifunctional device development. In this work, the morpho-structural and magnetic properties of all-spinel Fe3O4/MgCr2O4/Fe3O4 trilayers grown on an MgCr2O4 buffer layer, exhibiting very close lattice matching, were investigated using ...
