Plasmonic Bi‐Cavity Nanostructure for Efficient Light Collection and Localization
Analysis &Sensing, Volume 6, Issue 2, March 2026.Co‐tuning the plateau and pyramid lengths of a pyramid‐on‐plateau nanostructure creates a hybrid antenna‐cavity that efficiently couples low‐NA excitation and funnels energy to the apex, increasing nano‐Raman signal and enabling TERS in geometries previously inaccessible to high‐NA objectives.Tip‐enhanced Raman spectroscopy (TERS) typically relies on ...

Refractive Index Compensation in Over-Determined Interferometric Systems
Sensors, 2012 We present an interferometric technique based on a differential interferometry setup for measurement under atmospheric conditions. The key limiting factor in any interferometric dimensional measurement are fluctuations of the refractive index of air ...

Micro-displacement sensors based on plastic photonic bandgap Bragg fibers
, 2013 We demonstrate an amplitude-based micro-displacement sensor that uses a plastic photonic bandgap Bragg fiber with one end coated with a silver layer. The reflection intensity of the Bragg fiber is characterized in response to different displacements (or ...

Spatio‐Temporal Diversity of Calcium Activity in Microglia
Glia, Volume 74, Issue 3, March 2026.Ca2+ activity mostly occurs in microglial processes and stays localized. When it spreads, it often shows a directional bias and is constrained by branch points. Activity strongly relies on P2Y12 receptors and is shaped by neuronal activity. ABSTRACT Microglia, the brain's innate immune cells, possess complex, highly motile branched processes. These act
