Deep‐Learning‐Based Denoising for Improved Phase Precision in Electron Holography of Electromagnetic Fields in Nanoscale Materials

Advanced Science, EarlyView.
Low‐dose electron holography is limited by shot noise, which buries weak phase signals. HoloDenoiser, a physics‐informed network that works simultaneously in the spatial and frequency domains, locates and protects the holographic sideband while suppressing noise in the hologram.

Passive Metasurface Tweezers for Multi‐Scale Orbital Transport and Trapping on Elastic Plates

Advanced Science, EarlyView.
Passive labyrinthine phase encoding converts single‐channel excitation into localized flexural‐wave vortices with programmable orbital angular momentum. The resulting vortex fields enable cross‐scale particle manipulation, including orbital transport, central confinement, and rotational actuation.

Polarization Holographic 4D Phenotyping Reveals Nanoplastic Induced Dysfunction in Zooplankton

Advanced Science, EarlyView.
Contaminant‐induced dysfunction in complex aquatic organisms remains difficult to resolve across scales. Polarization Holographic Imaging Microscopy (PHIM) integrates polarization‐sensitive holography with computational volumetric reconstruction for label‐free phenotyping of zooplankton in natural seawater, revealing that nanoplastic stress drives ...

Single‐Pulse Femtosecond Laser 3D Multi‐Foci Light‐Field Engineering via Multi‐Layer Noise Threshold Filtering

Advanced Science, EarlyView.
This study presents a single‐pulse femtosecond laser strategy for three‐dimensional multi‐foci light‐field shaping and high‐throughput micro/nano manufacturing. The multi‐layer noise threshold filtering algorithm improves focal quality, while the multi‐layer over‐sampling algorithm increases focal density.

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

Advanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...
