Real‐Time and High‐Resolution NIR‐II‐L Imaging of Netrin‐1‐Mediated Neurovascular Coupling Driven by Dose‐Dependent Electroacupuncture

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
Disrupted neurovascular coupling contributes to ovarian dysfunction in polycystic ovary syndrome. Using near‑infrared II long‑wavelength imaging, this study visualizes how electroacupuncture dynamically regulates ovarian blood vessels in vivo. Immediate and cumulative stimulation elicit distinct vascular responses via a Netrin‐1 dependent mechanism ...

Metal‐Enhanced Fluorescence for the Biologist's Cellular Imaging Toolkit: Design Principles and Recent Applications

open access: yesBioEssays, Volume 48, Issue 4, April 2026.
Metal‐enhanced fluorescence (MEF) harnesses plasmonic interactions between fluorophores and metal nanostructures to increase excitation and/or radiative decay rates, yielding brighter, more photostable fluorescence signals for cellular imaging. This review highlights how nanoparticle size, shape, distance, and spectral overlap govern enhancement versus
