Advanced Functional Materials, EarlyView.A 3D nanowire‐network SERS substrate with robust adhesion is developed, featuring pronounced z‐direction optical activity, ultralow detection limit (1.5 × 10−13 M), and excellent signal uniformity (RSD < 10%). Enabled by enhanced light scattering, increased optical density of states, and structural reinforcement, the substrate demonstrates stable, high‐

Fluorescence monitoring of capilarry electrophoresis separation in a lab-on-a-chip with monolithically integrated waveguides [PDF]
, 2008 Femtosecond-laser-written optical waveguides were monolithically integrated into a commercial lab-on-a-chip to intersect a microfluidic channel. Laser excitation through these waveguides confines the excitation window to a width of 12 μm, enabling high ...

Advanced Functional Materials, EarlyView.Alumina growth narrows surface pores and seals non‐selective defects, enhancing selectivity while preserving the nanoporous graphene architecture. Additionally, the deposition enables gradient‐controlled structural modification, with intergrown alumina acting as a physical cross‐linker that stabilizes the laminar structure.

Advanced Healthcare Materials, EarlyView.Human iPSC‐derived hypertrophic chondrocyte sheet promotes bone regeneration. Abstract Bone defects are a major clinical challenge, primarily owing to the limited self‐healing capacity of bones and the high risk of complications associated with conventional treatment strategies.

Strain sensing based on radiative emission-absorption mechanism using dye-doped polymer optical fiber [PDF]
, 2017 A stress sensor based on a dye-doped polymeric optical fiber is able to detect stress by simple comparison of two luminescence peaks from a pair of energy transfer organic dyes. Coumarin 540A (donor) and Rhodamine 6G (acceptor) were doped in the core and

Advanced Materials Interfaces, EarlyView.Quantum‐confined lepidocrocite titanate nanofilaments are doped, bottom‐up, with Mn+2, Fe+2, Co+2, Ni+2, and Cu+2 to tune electronic structure and catalysis. Doping narrows the bandgap—by up to ∼0.8 eV—and extends visible absorption. Ni‐doped filaments accelerate oxygen evolution (319 mV at 10 mA cm−2) and TM‐doped samples rapidly degrade rhodamine 6G (
