Two‐Photon Endomicroscopy for Image‐Guided Magnetic Micro‐Agents

Small, EarlyView.
Image‐guided manipulation of magnetic micro‐agents requires localized fluorescence feedback capable of resolving dynamic interactions in confined environments. This study introduces a two‐photon endomicroscopy platform for real‐time motion tracking, multicolor micro‐agent discrimination, and imaging through biological tissue.

PDA‐Engineered 3D‐Printed Polymer–ZrO2 Hybrid Scaffolds Enabling Enhanced Radiopacity, Photothermal Therapy, and Cell Migration Modulation

Small, EarlyView.
A multifunctional 3D‐printed polymer–ZrO2 scaffold is developed to provide intrinsic radiopacity, photothermal responsiveness, and surface bioactivity. Reinforcement with ZrO2 enables real‐time x‐ray visibility and mechanical robustness, while a polydopamine coating facilitates near‐infrared‐triggered drug release and modulates cell migration, thereby ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems

Advanced Functional Materials, Volume 36, Issue 73, 10 September 2026.
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...

Mechanically Assisted Magnetic Actuation in Ceramic‐Based Microscrolls for Fast and Durable Soft Robotic Systems

Advanced Materials, Volume 38, Issue 52, 16 September 2026.
Ceramic‐based V2O5/Fe3O4 hybrid films are shaped into butterfly‐proboscis‐inspired microscroll actuators. Magnetic triggering initiates unrolling, while geometry‐programmed elastic strain energy drives rapid recoil, enabling fast, reversible, durable, and load‐bearing actuation under near‐field magnetic stimulation.
