Innovative Metasurface Colorimetric Cell‐on‐a‐Chip Sensor for Continuous, Label‐Free, Non‐Destructive Assessment of Intestinal Barrier Dynamics

Advanced Science, EarlyView.
We developed a real‐time, label‐free, high‐throughput cell‐on‐a‐chip system based on a metasurface plasmon resonance colorimetric sensor (MetaSPRCS) to evaluate intestinal barrier function. This platform enables continuous monitoring of cell adhesion, proliferation, and barrier layer formation, disruption, and repair.

Surface Plasmon Enhanced Photoluminescence of Carbon Dots Formed In Situ on Silver Gratings

Advanced Science, EarlyView.
Carbon emitters formed in situ on a silver grating via plasmonic catalysis yield enhanced spontaneous emission by preferential radiative decay into surface plasmons. Enhancement manifests as emission exhibiting characteristics of coherence (polarization, directionality), and accelerated lifetimes of ∼30 ps, yielding Purcell factors of ∼70.

Light‐Harvesting Photothermal Hotspots Enabled by NIR Scattering‐Absorption Coupling

Advanced Science, EarlyView.
By coupling the broadband scattering of nanodiamonds with the plasmonic absorption of gold nanostars, this work proposes a novel strategy for the active modulation of photon transport. This strategy creates localized photothermal hotspots in turbid media and achieves a supra‐additive heating efficiency, thereby providing a universal platform for low ...

Dual‐Band Modulation of Emissivity and Solar Transmittance Through Chemical Composition‐Tuned Asymmetric Layer‐by‐Layer Assembly

Advanced Science, EarlyView.
An unconventional asymmetric Layer‐by‐Layer (LbL) assembly technique was developed to fabricate a Fabry‐Pérot (F‐P) resonator, which enhances luminous transmittance (Tlum) and enables dual‐band modulation in both the near‐infrared (NIR) and mid‐infrared (MIR) regions.
