Photoacoustic Microscopy for Multiscale Biological System Visualization and Clinical Translation

Advanced Science, EarlyView.
Photoacoustic microscopy (PAM) is a powerful biomedical imaging tool renowned for its non‐invasiveness and high resolution. This review synthesizes recent technological advances and highlights their broad applications from cellular and organ‐level to whole‐animal imaging.

In vivo photoacoustic imaging dynamically monitors the structural and functional changes of ischemic stroke at a very early stage

Theranostics, 2020
Ischemic stroke (IS) is one of the leading causes of death and accounts for 85% of stroke cases. Since the symptoms are not obvious, diagnosis of IS, particularly at an early stage, is a great challenge. Photoacoustic imaging combines high sensitivity of

A variational method for quantitative photoacoustic tomography with piecewise constant coefficients

, 2015
In this article, we consider the inverse problem of determining spatially heterogeneous absorption and diffusion coefficients from a single measurement of the absorbed energy (in the steady-state diffusion approximation of light transfer).

Fluorinated Hypoxia‐Responsive Aza‐BODIPY for NIR‐II FL/19F MR/PA Imaging and Phototherapy of Lung Cancer

Advanced Science, EarlyView.
Fluorinated N‐oxide aza‐BODIPY nanoemulsions integrate fluorination‐driven molecular design with co‐assembly in fluorinated oil for multimodal imaging‐guided phototherapy. The co‐assembly redshifts fluorescence into the NIR‐II window for deep‐tissue imaging and provides a unified 19F signal for background‐free, quantitative MRI.

Effects of optical attenuation, heat diffusion and acoustic coherence in photoacoustic signals produced by nanoparticles

, 2018
Behavior of the photoacoustic signal produced by nanoparticles as a function of their concentration was studied in detail. As the concentration of nanoparticles is increased in a sample, the peak-to-peak photoacoustic amplitude increases linearly up to a

In Situ Synthesis of a Tumor Microenvironment‐Activated Radiosensitizing Cu2‐xS/LDH Probe for Photoacoustic Imaging‐Guided Radiotherapy

Advanced Science, EarlyView.
We reported a new kind of organic‐inorganic composite nanomaterial with excellent PA imaging performance after the in situ activation by hydrogen sulfide in colorectal cancer tissues, which was used for precise radiotherapy of colorectal cancer. It shows a great application potential for early diagnosis and treatment of tumor.

Engineering Plasmonic Nanoparticles for Enhanced Photoacoustic Imaging.

ACS Nano, 2020
Photoacoustic (PA) imaging is an emerging imaging modality whereby pulsed laser illumination generates pressure transients that are detectable using conventional ultrasound. Plasmonic nanoparticles such as gold nanorods and nanostars are often used as PA

Deep Learning‐Assisted Coherent Raman Scattering Microscopy

Advanced Intelligent Discovery, EarlyView.
The analytical capabilities of coherent Raman scattering microscopy are augmented through deep learning integration. This synergistic paradigm improves fundamental performance via denoising, deconvolution, and hyperspectral unmixing. Concurrently, it enhances downstream image analysis including subcellular localization, virtual staining, and clinical ...
