Rapid Fabrication of Self‐Propelled and Steerable Magnetic Microcatheters for Precision Medicine

Advanced Materials, Volume 38, Issue 51, 11 September 2026.
A rapid Joule heating fabrication method for the production of self‐propelling, adaptive microcatheters, with tunable stiffness and integrated microfluidic channels is presented. Demonstrated through three microrobotic designs, including a steerable guiding catheter, an untethered wave‐crawling TubeBot, and a distal‐end propelled microcatheter, it was ...

In‐Process Magnetization for 3D Printing of Magnetorheological Elastomer with Heterogeneous Magnetic Profile for Anisotropic Actuation

Advanced Science, Volume 13, Issue 50, 7 September 2026.
Fully programmable, in‐process 3D magnetization integrated with multi‐material printing enables soft magnetic systems with precise actuation and sensing. Discrete and continuous magnetization profiles drive bending, morphing, and locomotion, demonstrated through strain‐sensing elements, dragonfly‐inspired wings, octopus‐like tentacles, and a serpentine

Two-dimensional coordination risedronate-manganese nanobelts as adjuvant for cancer radiotherapy and immunotherapy

Nature Communications
The irradiated tumor itself represents an opportunity to establish endogenous in situ vaccines. However, such in situ cancer vaccination (ISCV) triggered by radiation therapy (RT) alone is very weak and hardly elicits systemic anticancer immunity.

Enhancing Selectivity of AuCu Electrocatalysts for CO2 Electroreduction in Chloride Electrolyte

ChemCatChem, Volume 18, Issue 17, 14 September 2026.
Synergistic effects of Au–Cu bimetallic electrocatalysts in chloride electrolytes were studied by combining experiments and computational modeling. Electrocatalysts were electrodeposited on GDEs and tested in KHCO3 and KCl electrolytes. AuCu and Au2Cu improved CO production in KCl, reaching up to 80% faradaic efficiency.
