Deep‐Learning‐Driven High‐Fidelity In Vivo Hyperspectral Fluorescence Imaging Under Extreme Photon‐Limited Conditions

open access: yesAdvanced Science, EarlyView.
Highly overlapping fluorescent signals become distinguishable in photon‐limited living organisms via advanced imaging with intelligent reconstruction. The resulting in vivo hyperspectral imaging capability reveals nanoplastic uptake and circulation in live zebrafish, providing a new approach for studying complex biological and environmental processes ...

Single‐Sensor Vibration Sensing in Anisotropic Composites Enabled by Disordered Metasurfaces

open access: yesAdvanced Science, EarlyView.
This work develops a single‐sensor vibration sensing (SSVS) framework that integrates disordered metasurfaces with compressive sensing. Comprehensive numerical and experimental validations demonstrate that, by manipulating anisotropic guided wave propagation through metasurfaces, the proposed SSVS framework enables high‐fidelity multi‐source vibration ...

Bypassing Heteronuclear MRI: Metal‐Free Organosilicon Nanotracers for Background‐Free Hotspot 1H Imaging on Clinical Hardware

open access: yesAdvanced Science, EarlyView.
Organosilicon micelles enable background‐free molecular magnetic resonance imaging (MRI) while remaining fully compatible with standard proton (1H) hardware. By exploiting a spectrally silent 1H window at ∼0 ppm, the silicone nanotracer allows hotspot detection by 1H chemical‐shift imaging (CSI) without metals or heteronuclei, enabling direct overlay ...

Unipolar Barrier Near‐Infrared 2D Photodetectors for 3D Image Sensors

open access: yesAdvanced Science, EarlyView.
A MoTe2/WSe2/Cl–SnSe2 unipolar barrier photodetector is demonstrated, in which the WSe2 layer effectively blocks majority‐carrier injection, yielding suppressed dark current and enhanced near‐infrared (NIR) sensing. The device achieves high detectivity, a wide linear dynamic range, and fast response under 1310 nm illumination, enabling high‐fidelity 3D

Battery‐Inspired Electrochemical Synapses for Neuromorphic Applications

open access: yesAdvanced Science, EarlyView.
Battery‐ion‐inspired synaptic devices integrate diverse electrolyte systems (solid, ion‐gel, liquid) with transition metal oxides, two‐dimensional materials, and organic channels to regulate ion‐electron coupling. By tailoring ion transport and host interactions, these platforms enable controllable plasticity and energy‐efficient implementations for ...
