Far‐infrared irradiation attenuates platelet‐derived growth factor‐stimulated vascular smooth muscle cell migration through protein phosphatase 2A‐mediated Akt inhibition

Photochemistry and Photobiology, EarlyView.
FIR irradiation enhances the physical association between Akt and PP2Ac in VSMCs, independent of the hyperthermal effect of FIR rays. The increased binding between Akt and PP2Ac induced by FIR irradiation facilitates the dephosphorylation of Akt at Ser473.

Lithium Niobate Quadratic Integrated Nonlinear Photonics: Enabling Ultra‐Wide Bandwidth and Ultrafast Photonic Engines

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This perspective surveys emerging quantum and classical photonic applications across operating wavelengths and timescales, highlighting persistent technological gaps in integrated light sources. We examine the unique advantages of quadratic nonlinear photonics on the thin‐film lithium niobate (TFLN) platform and discuss strategies for realizing ...

Ultrasensitive Tunable Terahertz Sensor via Critical Coupling‐Enhanced Fano Resonance

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
This work presents a hybrid terahertz sensor via the combination of graphene‐strip metasurface, cavity resonance, and gold film polaritons. The sensor achieves critical coupling with an ultrahigh‐Q resonance and tunable FOM with stable high sensitivity via gate voltage regulation, exhibiting excellent performance for on‐chip integrated biochemical ...

Broadband and Wide‐Angle Nonreciprocal Electromagnetic Transport via Gradient Permeability‐Near‐Zero Metastructures

Nanophotonics, Volume 15, Issue 9, 13 May 2026.
ABSTRACT Breaking time‐reversal symmetry to achieve broadband and wide‐angle nonreciprocity is critical in electromagnetic waves manipulation. While Epsilon‐Near‐Zero materials have revolutionized the control of Transverse Magnetic modes, realizing comparable broadband nonreciprocity for Transverse Electric (TE) modes remains a formidable challenge ...
