Measuring the Dynamic Nanometric Contact Radius of a Single Microdroplet on an Electrified Microinterface

Angewandte Chemie, EarlyView.
Electrochemical measurements as single aqueous microdroplets collide with electrode interfaces reveal nanoscale wetting dynamics. By tuning electrostatic repulsion, we control contact formation and probe surface interactions well beyond the optical diffraction limit.

Protein‐Template Gold Nanoclusters Induce Differentiation and Modify the Functional Properties of Primary Astrocytes

Advanced NanoBiomed Research, EarlyView.
The incubation of primary astrocytes with fAuNCs‐BSA induces: (A) long‐term effects including fAuNCs‐BSA internalization, red cell fluorescence, differentiation, upregulation of Ca2+ signaling, Cl‐current, and cell volume regulation. B) Short‐term (200 ms) stimulation with UV LED light increases in Ca2+ signaling and inhibition of K+ current. Astrocyte

Nanomaterial‐Mediated Near‐Infrared Photothermal Neuromodulation for Neurologic Disorders

Advanced NanoBiomed Research, EarlyView.
This review summarizes how near‐infrared light activates photothermal nanomaterials to enable noninvasive neuromodulation with high spatiotemporal precision. It elucidates the underlying mechanisms, explores targeted therapeutic applications for neurological disorders, discusses integration with optogenetics and biosensors, and addresses future ...

Two‐Nanosensor Electrochemical Profiling of Catecholamine Vesicle Interactions With Acute and Chronic Stress Granules in Living Cells

Angewandte Chemie, EarlyView.
A two‐nanosensor electrochemical strategy quantitatively distinguishes reactive oxygen species (ROS) in stress granules (SGs) from catecholamines in vesicles inside living cells. Chronic SGs formed under prolonged stress show elevated ROS and slower release, consistent with SG aging, and promote neurotransmitter loading likely through vesicle fusion ...
