Emerging Human‐Based Research Technologies for Investigating the Pathomechanisms and Therapies for Vascular Diseases

iNew Medicine, EarlyView.
ABSTRACT It is estimated that a large proportion of drug candidates fail in human clinical trials, mainly because animal models cannot fully replicate human disease and because of differential responses to various medications between humans and animals.

Generating Helical Polymorphic Beams Using Dielectric Metasurfaces

Laser &Photonics Reviews, EarlyView.
Helix‐shaped polymorphic beams are optical fields whose intensity maxima spiral around the propagation axis, enabling particle manipulation through attractive or repulsive forces. Traditionally requiring expensive spatial light modulators, metasurfaces now provide a compact, cost‐effective alternative. This work demonstrates general helical polymorphic

Femtosecond‐Laser‐Inscribed Cladding Fiber Bragg Gratings: Architectures, Design Trade‐Offs and Future Sensing Opportunities

Laser &Photonics Reviews, EarlyView.
Femtosecond‐laser inscription enables precise positioning of fiber Bragg gratings within the cladding, introducing new spatial and modal design freedoms. Auxiliary‐waveguide, near‐core evanescent‐field, and direct cladding‐mode‐excitation architectures provide complementary pathways toward multiparameter, vector, distributed, and environmentally ...

Micro‐ and Nanopatterning of Highly Conductive PEDOT Thin Films

Macromolecular Rapid Communications, EarlyView.
This work presents micro‐ and nanoscale fabrication strategies for organic thin‐film devices using non‐commercial PEDOT synthesized by V2O5‐mediated oxidative polymerization. Optimized films show controlled thickness and tunable conductivity. At the nanoscale, nanosphere lithography enables large‐area hexagonally packed PEDOT nanopillar arrays down to ...

Organoid Coculture Models for Cancer Research and Immunotherapy

Med Research, EarlyView.
This review summarizes organoid coculture platforms, including submerged Matrigel culture, air–liquid interface, microfluidic/organoid‐on‐a‐chip, and 3D bioprinting, for reconstructing the tumor microenvironment to study tumor–stroma/immune crosstalk, evaluate immunotherapies, and enable drug screening.

Influence of sulfonation degree and deposition technique on the electrical and morphological properties of sulfonated polystyrene thin films

Polymer International, EarlyView.
Sulfonated polystyrene films with different degrees of sulfonation were fabricated using Langmuir–Schaefer and drop‐casting techniques. Both the deposition method and sulfonation level strongly affect film morphology and electrical response, governing the performance of these materials as ammonia gas sensors.
