2D van der Waals System Integrated with Targeting Radio‐Diagnostic and Imaging Functions

open access: yesSmall, EarlyView.
Layered double hydroxide (LDH) nanoplates were engineered for tumor‐targeted imaging and therapy. By exploiting folate receptor (FR) expression levels, the system achieves selective tumor accumulation and high‐resolution dual PET/fluorescence (PET/FL) imaging.

Rapid scanning wide-field clutter elimination in epi-optoacoustic imaging using comb LOVIT.

open access: yes, 2018
Epi-style optoacoustic (OA) imaging provides flexibility by integrating the irradiation optics and ultrasound receiver, yet clutter generated by optical absorption near the probe obscures deep OA sources.

A Generalized Automated Framework for Thermal Characterization: From Bulk Materials to Complex Heterostructures

open access: yesSmall, EarlyView.
An automated MATLAB framework for inverse photoacoustic analysis enables precise thermal characterization of complex multilayer films. Application to electrodeposited CuxSe reveals a stoichiometry‐dependent thermal conductivity governed by lattice anharmonicity, not grain‐size scattering, in these superionic materials. ABSTRACT Precise determination of

Biomimetic TME‐Responsive Nanotheranostics for Precise NIR‐II Ratiometric Photoacoustic Imaging and Synergistic Immuno‐Photothermal Therapy

open access: yesSmall, EarlyView.
A biomimetic Au/Ag@HMON‐NLG@CCM nanotheranostic is engineered for tumor microenvironment‐responsive NIR‐II ratiometric photoacoustic imaging and immune‐photothermal therapy. The integration of hyperthermia‐triggered immunogenic cell death with IDO‐blockade‐mediated metabolic remodeling promotes dendritic cell maturation and T‐cell activation.

Engineering Nanoemulsions to Maximize NIR‐II Fluorescence and Preserve Photothermal Performance of a Novel Boron Difluoride Formazanate Dye

open access: yesAngewandte Chemie, Volume 138, Issue 25, 15 June 2026.
An oil‐in‐water nanoemulsion transforms a boron difluoride formazanate (BDF) dye into a dual‐modal imaging‐guided theranostic agent (BDF‐NE). Its nonpolar oil core maximizes NIR‐II fluorescence while maintaining strong photoacoustic contrast to guide photothermal therapy with high photostability and 66.8% photothermal conversion efficiency, achieving ...

X-Ray and Photoacoustic Studies on Zircaloy-2

open access: yes, 2011
Zircaloy-2, an useful nuclear material is studied here by photoacoustics to correlate with the measurements of X-rays. The microstructure variations observed in X-rays could be explained on the basis of thermal diffusivity measured by photoacoustics ...

Carbon monoxide‐triggered near‐infrared photoacoustic‐fluorescent integrated visualization tool for auxiliary diagnosis of heart failure and evaluation of reversal drug efficacy

open access: yesSmart Molecules, EarlyView.
An activatable metal‐free probe CS‐CO enables the first non‐invasive photoacoustic/fluorescence visualization of carbon monoxide (CO) fluctuations during heart failure and its reversal, linking CO levels directly to disease status. Abstract Heart failure (HF), a major global health challenge with high morbidity and mortality, lacks effective biomarkers
