Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

Advanced Materials, EarlyView.
Liquid metal‐based microrobots combine magnetic steering, intrinsic X‐ray visibility and softness, to navigate blood vessels even against flow. Under clinically relevant magnetic fields, liquid metal microrobots roll along vessel walls, cross endothelial barriers, and accumulate in target tissues.

Topology and Material Optimization in Ultra‐Soft Magneto‐Active Structures: Making Advantage of Residual Anisotropies

Advanced Materials, EarlyView.
Residual magnetization induces pronounced mechanical anisotropy in ultra‐soft magnetorheological elastomers, shaping deformation and actuation even without external magnetic fields. This study introduces a computational‐experimental framework integrating magneto‐mechanical coupling into topology optimization for designing soft magnetic actuators with ...

Rewriting Polymer Fate via Chemomechanical Coupling

Advanced Materials, EarlyView.
This work introduces a life‐like “living” polymer platform that can grow, degrow, and reprogram its properties after fabrication. By integrating mass transport, reversible polymerization, and controlled catalysis, the material achieves on‐demand changes in size, shape, and mechanical properties.

DNA Origami‐Templated Aptamer Chiral Structures Realize Cellular Enantioselectivity

Advanced Materials, EarlyView.
Aptamers displayed on tubular DNA origami nanostructures in defined chiral orientations (left‐ or right‐handed) exhibit enantioselective interactions with cell surface target proteins. While the right‐handed configuration supports only transient binding, the left handedness energetically favors protein dimerization and promotes subsequent ...

Holographic Whole‐Object Photopolymerization Preserving Director Alignment in Liquid Crystalline Actuators

Advanced Materials, EarlyView.
Holographic microlithography enables the fabrication of fully connected 3D liquid crystalline structures in a single exposure. The process maintains precise control over the director orientation within the entire object, preventing local director distortions typically observed in sequential printing.
