Tunable magnetic-luminescent Tb:SiO2@Fe3O4 nanoparticles for theranostic applications

European Mechanical Science
Magnetic-luminescent Tb-doped SiO2@Fe3O4 core@shell nanoparticles were synthesized via a two-step approach and evaluated for biomedical applications. Photoluminescence (PL) analysis showed broad emissions from the SiO2 matrix and distinct Tb3+-related ...

Qualitative Evaluation of the Magnetocrystalline Anisotropy in Spinel Ferrite Nanoparticles Using Polarized Neutron Powder Diffraction

Small, EarlyView.
Polarized neutron powder diffraction is used to qualitatively probe the magnetocrystalline anisotropy of cobalt‐doped ferrite nanoparticles. The analysis of local magnetic susceptibility tensors and magnetization ellipsoids reveals how cobalt incorporation modifies both the magnitude and orientation of anisotropy, providing a new approach to compare ...

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...

Reverse Thermo‐Responsive Nanoshells: The Interplay Between the Composition of Their Building Blocks and Their Temperature‐Responsive Morphing

Israel Journal of Chemistry, Volume 66, Issue 4, July 2026.
The graphical abstract shows hollow polymeric nanoshells from crosslinked PEO–PPO–PEO with methacrylate end‐groups. These shells expand at low temperatures (6 °C, ∼310 nm) and shrink at 37 °C (∼35 nm)—a 700‐fold volume change. This reverse thermo‐responsiveness, driven by polymer coiling–uncoiling, enables potential biomedical applications like ...

Bright Ferritin for Non‐Invasive MRI Monitoring of the Fate of Transplanted hPSC‐Cardiomyocytes in the Infarcted Rat Heart

Magnetic Resonance in Medicine, Volume 96, Issue 1, Page 323-338, July 2026.
ABSTRACT Purpose To demonstrate that a recently reported bright ferritin magnetic resonance imaging (MRI) platform can track transplanted human pluripotent stem cell (hPSC)‐derived cardiomyocytes (hPSC‐CMs) longitudinally and on‐demand in the rat heart.

Stimuli‐Responsive Hydrogels for Optical Applications: Mechanisms, Architectures, and Translational Challenges

Aggregate, Volume 7, Issue 6, June 2026.
The review discusses stimuli‐responsive hydrogels as soft optical materials that translate physical, chemical, and biological cues into refractive‐index, scattering, birefringence, diffraction, and transparency changes. It examines major stimulus classes and photonic architectures for biosensing, waveguiding, adaptive lenses, smart windows, and therapy.
