Dual Modality Semiconducting Polymer Nanoparticles for Use in Optical and Magnetic Resonance Imaging

Advanced NanoBiomed Research, Volume 6, Issue 2, February 2026.
Well‐defined dual‐modality semiconducting polymer nanoparticles composed of red‐emitting conjugated polymers functionalized with novel gadolinium‐based contrast agents have been prepared. The assemblies show a greatly enhanced relaxivity performance compared to the clinical standard, Dotarem, while offering ultrabright fluorescence, ideal for optical ...

Time‐Resolved Fluorescence and Diffuse Reflectance (TRF‐DR) Spectroscopy for Heterogeneous Breast Tissue Classification and Tumor Margin Assessment

Journal of Biophotonics, Volume 19, Issue 2, February 2026.
This study demonstrates our time‐resolved fluorescence and diffuse reflectance spectroscopy system can classify breast tumor in heterogeneous tissue. It achieved sensitivity and specificity comparable to other techniques and highlights the effect of heterogeneous measurements on performance.

A Compact Highly Sensitive Cone–Sphere Photoacoustic Spectroscopy Sensor for Real-Time Detection of Dissolved Acetylene in Transformer Oil

Photonics
In this work, we report a compact and highly sensitive photoacoustic spectroscopy (PAS) system based on a cone–sphere coupled photoacoustic cell (CSC-PAC) for real-time detection of trace acetylene (C2H2) dissolved in transformer oil.
