Extrusion‐Based Bioprinting of Living Bioinks for Tissue and Organ Engineering

open access: yesAdvanced Materials Technologies, EarlyView.
Extrusion‐based bioprinting is presented as the most versatile route for fabricating living, heterogeneous tissues. Its ability to combine diverse bioinks, support matrices, and advanced printhead geometries transforms familiar constraints into powerful biofabrication opportunities.

Autonomous Reconfigurable Modular Conductive Hydrogels for Adaptive and Degradable Bioelectronic Interfaces

open access: yesAdvanced Materials Technologies, EarlyView.
Bridging rigid electrodes with soft, irregular tissues demands more than conductivity alone. Modular conductive hydrogels autonomously reconfigure into conformal electrode‐tissue interfaces, coupling mixed ionic‐electronic conduction with tissue‐like mechanics, self‐healing, and degradability.

Red‐Light Tomographic Volumetric 3D Printing in Seconds for Fabrication of Colorless Structures

open access: yesAdvanced Materials Technologies, EarlyView.
A custom red‐light‐responsive TVAM platform combines methylene blue, triethanolamine, and PEGDA to fabricate transparent crosslinked hydrogels. Light patterns are projected into a rotating resin container, where a sacrificial photoinitiator system enables rapid polymerization and colorless channel‐containing structures, utilizing low‐energy light for ...

Microwall‐Integrated Terahertz Metasurfaces for Spatially Guided Label‐Free Sensing of Micrometer‐Scale Plastic Particles

open access: yesAdvanced Materials Technologies, EarlyView.
A THz metasurface device integrating a metal–dielectric–metal resonator with microwall‐defined recessed regions enables spatially guided, label‐free sensing of micrometer‐scale plastic particles. The as‐fabricated devices exhibit distinct THz reflection resonances for 3.1‐µm polystyrene particles and a concentration‐dependent resonance‐frequency‐shift ...

Basis‐Independent Geometric Phase Modulation in Circularly Birefringent Plasmonic Structures

open access: yesAdvanced Optical Materials, EarlyView.
Here we introduce a plasmonic metasurface composed of spatially rotated chiral spiral unit cells designed to produce space‐variant circular retardance. This generates a geometric phase ramp equivalent to a blazed grating, leading to polarization dependent diffraction orders in momentum space.

Strong Enhancement of Er3+ Emission at Room Temperature in Si3N4 Metasurfaces

open access: yesAdvanced Optical Materials, EarlyView.
Erbium‐doped SiN metasurfaces are engineered to support Mie resonances at 1.55μm$1.55\text{}\mathrm{\mu}\mathrm{m}$, enhancing the local density of optical states and accelerating spontaneous emission. By optimizing nanocylinder radius and implantation depth, room‐temperature PL is increased about 18‐fold, while lifetime shortens by nearly an order of ...
