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

Advanced 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.

One‐Component Carbon Dot Photoinitiator Enables High‐Fidelity Digital Light Processing 3D Printing With Improved Mechanical Resistance

Advanced Functional Materials, EarlyView.
Furfural carbon dots functionalized with acylphosphine oxide photosensitive groups (CD‐PO PI) demonstrate potential as one‐component photoinitiators for digital light processing (DLP) 3D printing. Compared to conventional diphenyl(2,4,6‐trimethylbenzoyl)phosphine oxide (TPO), CD‐PO PI offers improved printing resolution, resin toughness, and biological
