Flash Photodynamic Therapy – How the Saturation of Photosensitizer Absorption Enables Selective and Deeper Tumor Treatments

Advanced Science, Volume 13, Issue 1, 5 January 2026.
FLASH‐PDT uses strongly‐absorbing photosensitizers and pulsed lasers to saturate the photosensitizer absorption at ≈1‐cm tissue depths. This allows for the generation of [ROS] above the necrosis threshold level for tumors, while maintaining [ROS] in peritumoral tissues below that threshold, even when the tumor‐to‐peritumoral tissue ratio is as low as 2.

A Hybrid Diffusion Model Enhances Multiparametric 3D Photoacoustic Computed Tomography

Advanced Science, Volume 13, Issue 1, 5 January 2026.
The hybrid diffusion PACT (HD‐PACT) system enhances dynamic multiparametric information using only 128–256 ultrasound elements. By overcoming limited‐view artifacts, HD‐PACT refines structural and functional information such as oxygen saturation observed in 3D premium PACT with > 1000 elements. Through cost‐effective and faster multiparametric imaging,

Ultrasensitive Diamond Cantilever‐Based Optical Microphone

Advanced Science, Volume 13, Issue 3, 14 January 2026.
The first demonstration that high quality diamond cantilevers function as high‐sensitivity acoustic transducers is reported, combining CVD diamond cantilevers and an extrinsic Fabry‐Perot optical configuration. High transduction efficiency yields record sensitivity (51.5 VPa−1) and MDP (0.018 µPa/Hz$\rm {\sqrt {Hz}}$), enabling durable, low‐noise ...

A Hypoxia‐Responsive Near‐Infrared Phosphorescence Nanoprobe for High‐Sensitive Detection of Tumor Cells and Imaging of Colorectal Cancer In Situ

Aggregate, Volume 7, Issue 1, January 2026.
We have successfully developed a hypoxia‐responsive near‐infrared phosphorescent probe, Ir‐PEG. This nanoprobe demonstrates high sensitivity, water solubility, and deep‐tissue penetration. It remains specifically activatable even in the hypoxic intestinal environment, facilitating high‐contrast imaging of orthotopic colon cancer.
