Multipolar Resonances in Electro‐Optic Metasurfaces with Moderate Refractive Index

Advanced Photonics Research, EarlyView.
Electro‐optic nanoantennas with moderate refractive indices of 2.3 to 3.0 are numerically shown to sustain strong multipolar resonances, enabling efficient light confinement and EO tuning. Multipolar modes of even parity are most sensitive to variations in the refractive index.

Integrated Flexible Zwitterionic Electrochemical Sensor Platform for Real‐Time Salivary Glucose Quantification

Advanced Sensor Research, EarlyView.
A flexible electrochemical sensor platform can enable continuous, real‐time monitoring of salivary glucose for applications confined to spaces such as the oral cavity. Surface modifications with Prussian blue, chitosan, and zwitterionic polymers enhance sensitivity, selectivity, and antiadherent performance.
