Ultrasound‐Boosted Liposomal Prodrug Overcomes Age‐Associated Biodistribution Disparity in Pediatric Solid Tumor Therapy

open access: yesAdvanced Science, EarlyView.
The age‐associated disparity of nanocarrier biodistribution limits the nanotherapeutics of childhood solid tumors. This study developed an ultrasound‐activated liposomal prodrug (CSCPTL) to overcome the age‐associated disparity of off‐target distribution.

ERM Inhibition Confers Ferroptosis Resistance through ROS‐Induced NRF2 Signaling

open access: yesAdvanced Science, EarlyView.
ERM inhibition disrupts ERM‐actin interactions, elevating ROS and triggering KEAP1 degradation, which stabilizes and activates NRF2. Nuclear NRF2 induces cytoprotective genes, notably HMOX1, enhancing redox buffering and suppressing lipid peroxidation to resist erastin‐induced ferroptosis.

Miniature Robotic Swimmer with Precise 2D Motion Control via Acoustic Vortex‐Induced Propulsion

open access: yesAdvanced Science, EarlyView.
In this work, a miniature robotic swimmer achieves precise 2D motion using sound waves with customized 3D‐printed lenses. Localized acoustic vortices drive both translation and rotation of the swimmer without mechanical parts. This contactless approach offers a novel route to controlled micro‐scale movement, with promising applications in biomedical ...

Machine Learning Discovery of Record‐Low Lattice Thermal Conductivity in Double Perovskites

open access: yesAdvanced Science, EarlyView.
 A deep learning interatomic potential is introduced to predict forces for computing phonon properties and thermal transport behavior in double perovskites. Screening 9,709 compounds identifies 1,597 stable materials, and Boltzmann transport calculations including both three and four‐phonon scattering suggests a record‐low lattice thermal conductivity ...
