Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

open access: yesAdvanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

open access: yesAdvanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

A Noninvasive Approach to Study Localized Forces in 3D Epithelia

open access: yesAdvanced Materials, EarlyView.
Epithelial morphogenesis depends on dynamic mechanical coupling between adhesion complexes and the cytoskeleton, yet its regulation in polarized 3D tissues remains elusive. We developed a noninvasive strategy using cell‐like elastic microbeads to quantify local forces in intact epithelia.

Plasmonically Enhanced Microarray Immunoassay for High‐Sensitivity Monitoring of Heart Failure

open access: yesAdvanced Materials, EarlyView.
A novel plasmonically enhanced PE‐D4 assay combines nanopatch antennas with a microarray immunoassay for the detection of heart failure biomarkers NT‐proBNP, NGAL, and galectin‐3 in complex biological samples. Plasmonic amplification substantially enhances fluorescence signals, enabling sensitive biomarker quantification with a low‐cost smartphone ...

Bioinspired Adaptive Artificial Cilia With Tunable Sensitivity and Dynamic Range for Airflow Monitoring in the Central Airway

open access: yesAdvanced Materials Technologies, EarlyView.
A magnetically reconfigurable airflow sensor integrated with an airway stent enables tunable sensitivity and dynamic sensing range. Airflow‐induced cantilever deformation generates resistance changes, while an external magnetic field modulates sensor stiffness, enhancing sensitivity at low airflow velocities and extending the sensing range at higher ...
