Interfacial Stress Regulates Plasticity and Drug Resistance at the Breast Cancer‐Host Interface

open access: yesAdvanced Science, EarlyView.
Drop‐on‐demand printing is used to replicate the spatial compartmentalization of the breast cancer‐host interface. Hydrogel confinement affects phenotypic changes in cells at the spheroid interface that drives a two‐fold increase in chemotherapeutic resistance compared to control unconfined spheroids.

Synergy between Defects and Lattice Distortion Drives Self‐Powered Elastico‐Near‐Infrared Mechanoluminescence in Cr3+‐Doped Spinel Oxides

open access: yesAdvanced Science, EarlyView.
This work demonstrates crystal lattice tailoring and defect modulation to engineer a Cr3+‐activated cubic spinel oxide, where strategic introduction of Cr3+ into octahedral Al3+/Li+ sites drives efficient NIR‐ML through a non‐trap‐based mechanism. Abstract Elastico‐mechanoluminescence (ML) enables unique force‐to‐light transduction for applications in ...
