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.

Advanced Materials, EarlyView.Heterophase fcc‐hcp‐fcc RuFeMMnMo (M═CoNi, Co, and Ni) high‐entropy alloy nanomaterials have been successfully synthesized using a one‐pot approach. The highly random distribution of multiple metal components and the tunable diversity of metal atomic arrangements can be realized simultaneously. By combining metals with different work functions, fcc‐hcp‐
