Nanomaterials Based on Fe₃O₄ and Phthalocyanines Derived from Cashew Nut Shell Liquid

Molecules, 2019
In this work we report the synthesis of new hybrid nanomaterials in the core/shell/shell morphology, consisting of a magnetite core (Fe3O4) and two consecutive layers of oleic acid (OA) and phthalocyanine molecules, the latter derived from cashew nut ...

Giant Direct Magnetoelectric Effect in Nanocomposite CoFe2O4:PVDF‐TrFE Thin Films

Advanced Science, EarlyView.
A novel three‐step grow‐etch‐fill fabrication approach creates structured cobalt ferrite/ferroelectric polymer nanocomposites with high interfacial areas. Driven by efficient strain‐mediated coupling, this crystalline system achieves a giant room‐temperature magnetoelectric coefficient nearly two orders of magnitude higher than other CFO/PVDF‐TrFE thin

Magnetically Guided Macrophage Immunobots Coordinate Iron‐Metabolic Cascades and Immunogenic Ferroptosis for Tumor Immunotherapy

Advanced Science, EarlyView.
Magnetically guided macrophage immunobots integrate active tumor targeting with immunometabolic therapy. After systemic administration, magnetic actuation enhances immunobot retention and tumor penetration, while LPS‐functionalized FePt microrollers sustain M1‐like polarization through inflammatory and iron‐amplified oxidative signaling and trigger ...

Closing the Loop: High‐Precision 3D Photofabrication in Living Tissues

Advanced Science, EarlyView.
Writing 3D microstructures inside living tissue demands more than laser access; It demands information. Hierarchical sensing captures thermal and mechanical states across pulse‐train, voxel, and structure timescales, feeding a controller that steers the laser in real time.
