Nanoamphizymes: Self‐Assembled Amphiphilic Enzymatic Nanomaterials for High‐Performance Biocatalysis and Biosensing

open access: yesAdvanced Functional Materials, EarlyView.
An amphiphilic GOx nanoamphizyme was constructed by covalently introducing hydrophobic PPNI linkers onto GOx, enabling spontaneous self‐assembly into tunable nanoparticles. Mild crosslinking further stabilized the assemblies and enhanced catalytic performance and stability.

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays

open access: yesAdvanced Functional Materials, EarlyView.
Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Effect of constructivist teaching in the improvement of midwives’ interpretation ability in fetal monitor graphs

open access: yesBMC Medical Education
Background Accurate interpretation of fetal monitoring results is particularly significant in dealing with safety issues during delivery. There are different education programs on fetal monitoring and the education effects are unsatisfactory.

Selenium‐Integrated Cyanine Dye With Enhanced Photophysical Properties for Optoacoustic‐Guided Cancer Imaging and Therapy

open access: yesAdvanced Functional Materials, EarlyView.
This study introduces selenium‐integrated cyanine dye (Se‐Cyn), with superior photostability, absorption, and photothermal efficiency, outperforming ICG in NIR window. Its nanoparticle form remains stable in water, accumulates in tumors, and enables strong optoacoustic imaging and effective phototherapy outcomes.

Single‐Cell Resolution Mapping of Osteoarthritis‐Associated Chondrocyte Dynamics Using a High‐Density CMOS MEA Platform

open access: yesAdvanced Healthcare Materials, EarlyView.
Single‐cell and spatially resolved impedance mapping using a high‐density CMOS‐MEA platform enables non‐invasive monitoring of osteoarthritis‐associated chondrocyte dynamics. Continuous label‐free measurements reveal heterogeneous remodeling behaviors, including proliferation, migration, and phenotypic transitions, establishing a powerful approach for ...

Atom‐Efficient Cerium‐Based Molecular Cages as Biocompatible Reactive Oxygen Scavengers

open access: yesAdvanced Healthcare Materials, EarlyView.
Discrete mixed‐valent cerium molecular cages organize accessible redox centers within confined coordination environments and scavenge superoxide, hydrogen peroxide, and hydroxyl radicals. Encapsulation of the lead cage in an ROS‐responsive DTP nanoplatform enables lesion‐associated delivery, attenuates macrophage oxidative stress and inflammation, and ...

Ionic Gating of Liquid‐Crystal‐Like Pteridine Assemblies Enables Tunable Light Scattering

open access: yesAdvanced Materials, EarlyView.
Tunable optical properties emerge through developmentally regulated ionic gating, which transforms disordered, ultraviolet (UV)‐absorbing organelles into concentrically ordered, liquid‐crystal‐like light scatterers. By integrating analyses of pteridine composition, potassium‐dependent assembly, hierarchical ultrastructure, and optical behavior, the ...

Generational Leaps in Intrapartum Fetal Surveillance

open access: yesDiagnostics
Background/Objectives: Electronic fetal monitoring (EFM) has been used for intrapartum fetal surveillance for over 50 years. Despite numerous trials comparing EFM with standard fetal heart rate (FHR) auscultation, it remains contentious whether ...
