Edible Pneumatic Battery for Sustained and Repeated Robot Actuation

Advanced Science, EarlyView.
This work presents an edible energy source and valve system to power soft, pneumatically driven edible robots. A chemical reaction between sodium bicarbonate and citric acid generates carbon dioxide gas, and a pressure‐triggered edible valve enables self‐repetitive motion of the edible actuator.

Therapeutic Reprogramming of Glioblastoma Phenotypic States Using Multifunctional Heparin Nanoparticles

Advanced Science, EarlyView.
This study presents heparin‐derived nanoparticles (HP‐NPs) as a novel precision medicine platform that combines therapeutic and delivery functions. HP‐NPs target drug‐resistant glioblastoma stem cells, reprogramming them into a drug‐sensitive phenotype and significantly reducing tumor progression.

Rapid Microfluidic Drug Sensitivity Testing Within 5 Days Using Minimal Clinical Tumor Samples

Advanced Science, EarlyView.
This study develops the air‐punched fabrication approach for nanoliter‐scale microcavity arrays with ultra‐smooth microcavity surfaces, with which rapid formation and 3D culture of tumor cell spheroids from small numbers of cell samples, as well as high‐throughput drug sensitivity testing can be achieved within 5 days.
