Label‐Free 3D Photoacoustic Imaging of Tumor Organoids for Volumetric Drug Screening

open access: yesAdvanced Science, EarlyView.
A label‐free organoid photoacoustic imaging (LFOPI) system is developed for precise volumetric drug screening evaluation. As a proof of concept, LFOPI's performance in chemotherapy and immunotherapy drug screening assays are further evaluated. The LFOPI offers unique non‐invasive, label‐free capabilities for tumor organoids, and contributes to the ...

Aging and the Spectral Properties of Brain Hemodynamics

open access: yesAdvanced Science, EarlyView.
As the brain ages, its metabolic demands decline—but not uniformly. Here, spectral slope flattening of resting‐state fMRI signals is proposed as a potential biomarker of pathologic brain aging. A subset of older adults diverges from youthful spectral and metabolic patterns, with changes linked to frontal white matter pathology and regional loss of ...

Interference Pattern Caused by Bilateral Bone Conduction Stimulation Impairs Sound Localization

open access: yesAdvanced Science, EarlyView.
This work explores how crosstalk‐induced wave interference affects bone conduction (BC) sound localization. Using a theoretical model, cadaveric vibrometry, and psychoacoustic tests, atypical BC lateralization patterns are revealed that contradict air conduction (AC) principles.
