An Open‐Source Pipeline for Calcium Imaging and All‐Optical Physiology in Human Stem Cell‐Derived Neurons

Advanced Science, Volume 13, Issue 26, 8 May 2026.
This work introduces an open‐source all‐optical platform for functional phenotyping of human stem cell‐derived neurons. The system integrates optogenetics, calcium imaging, automated acquisition, and analysis to resolve single‐cell and network activity, enabling longitudinal measurements, disease modeling, and pharmacological screening in preclinical ...

Octupolar AIEgens Photosensitizers With Enhanced Molar Absorptivity for Near‐Infrared Phototheranostics

Aggregate, Volume 7, Issue 5, May 2026.
Symmetry‐guided molecular engineering transforms dipolar AIEgens into octupolar AIEgens (D(A)3) with enhanced NIR‐II absorptivity. The octupolar architecture activates additional S0→S2 transitions and promotes efficient intersystem crossing, leading to strong reactive oxygen species generation.

Phase and absorbance retrieval in X‐ray holographic microscopy under weak illumination using physics‐driven neural networks

Journal of Synchrotron Radiation, Volume 33, Issue 3, Page 794-805, May 2026.
A physics‐driven deep learning model enables single‐shot retrieval of 3D phase and absorbance from shot‐noise‐limited hard X‐ray holograms. Validated on both synthetic and experimental data, it provides robust reconstruction under weak illumination.X‐ray holographic microscopy is a three‐dimensional (3D) imaging technique for nanoscale‐resolution ...
