Liquid Metal Microrobots for Magnetically Guided Transvascular Navigation

open access: yesAdvanced 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.

Mitochondria‐Specific Protein Delivery by Protease‐Triggered Release in Plants with Single‐Walled Carbon Nanotubes

open access: yesAdvanced Materials Technologies, EarlyView.
Polymer‐coated carbon nanotubes were engineered as protease‐responsive nanocarriers for protein delivery in intact plants. GFP cargo can be released by cytosolic phytaspase cleavage and subsequently targeted to mitochondria via an N‐terminal sequence, enabling controlled intracellular protein delivery without tissue damage and demonstrating stable ...

Multiobjective Codesign Optimization of a Planar Pneumatic Artificial Muscle‐Based Snake‐Like Robot for Enhanced Agility and Energy Efficiency

open access: yesAdvanced Robotics Research, EarlyView.
A codesign multiobjective optimization framework was developed to enhance the morphology and controller of a snake‐like robot driven by artificial muscles. It improved planar locomotion, agility, and power efficiency. The approach optimized link geometry and controller gains, revealing that shorter muscles near joints and longer linkages maximize ...
