Rolling and Impacting Caustic Drops on Super Liquid‐Repellent Surfaces: In Situ Force and Energy Monitoring of Surface Degradation

Advanced Functional Materials, EarlyView.
The use of continuous drop‐based force and energy probing methods is introduced to evaluate in situ chemical degradation of super liquid‐repellent surfaces by caustic liquids. By tracking the velocity of rolling drops and energy dissipation of impacting drops, degradation dynamics are resolved under high spatio‐temporal precision. Using this technique,

SiO2‐CaOCME/Poly(Tetrahydrofuran)/Poly(Caprolactone) 3D‐Printed Scaffolds Drive Human‐Bone Marrow Stromal Cell Osteogenic Differentiation

Advanced Healthcare Materials, EarlyView.
3D printed hybrid scaffolds combining bioactive silica–calcium chemistry with elastic polymers guide human bone stem cells to form bone. The scaffolds support cell survival, organization, and invasion while releasing osteogenic ions. Together, architecture and composition drive bone‐specific gene expression, extracellular matrix organization, and ...

Photosensitizing Lipid Nanoparticles for Ferroptosis‐Enhanced Photodynamic Cancer Therapy via GPX4 Silencing

Advanced Healthcare Materials, EarlyView.
Photosensitizing lipid nanoparticles (PLNPs) are engineered by incorporating cholesterol–PEG–pheophorbide a into MC3‐based LNPs and encapsulating GPX4‐targeting siRNA. Upon light activation, PLNPs generate reactive oxygen species (ROS) while silencing GPX4 to induce ferroptosis.
