Quantitative Photoacoustic Imaging in the Acoustic Regime using SPIM

, 2017
While in standard photoacoustic imaging the propagation of sound waves is modeled by the standard wave equation, our approach is based on a generalized wave equation with variable sound speed and material density, respectively.

Engineered Plasmonic and Fluorescent Nanomaterials for Biosensing, Motion, Imaging, and Therapeutic Applications

Advanced Materials, EarlyView.
A schematic illustration of how noble metals can be used to create nanoparticles (NPs) or nanoclusters (NCs). Noble metal NPs, due to their plasmonic properties, enable photothermal therapy and surface‐enhanced Raman scattering (SERS). In contrast, NCs, which lack a plasmonic resonance band, exhibit fluorescence, making them ideal for bioimaging ...

Exploiting Bacterial Pigmentation for Non-Destructive Detection of Seed-Borne Pathogens by Using Photoacoustic Techniques

Sensors
Seed-borne pathogens pose a significant threat to global food security. This study focuses on Curtobacterium flaccumfaciens pv. flaccumfaciens (Cff), a quarantine plant pathogen causing bacterial wilt of common beans.

In vivo photoacoustics and high frequency ultrasound imaging of mechanical high intensity focused ultrasound (HIFU) ablation.

Biomedical Optics Express, 2017
The thermal effect of high intensity focused ultrasound (HIFU) has been clinically exploited over a decade, while the mechanical HIFU is still largely confined to laboratory investigations.

Sonodynamic and Bioorthogonal Sonocatalytic Thrombotic Therapy Based on AIE Cationic Tetranuclear Ir(III) Complex Nanoplatform Guided by NIR‐Chemiluminescence Imaging

Advanced Materials, EarlyView.
AIE‐active tetranuclear Ir(III) complex Ir‐4 as a sonosensitizer/sonocatalyst is formulated into a nanoplatform with an H2S donor. Ir‐4@S‐R NPs achieves combined endogenous NIR chemiluminescence imaging, sonodynamic therapy and release of H2S in situ by a bioorthogonal sonocatalytic reaction in vivo, achieving safe thrombolysis and anti‐inflammatory ...

Specific imaging of atherosclerotic plaque lipids with two-wavelength intravascular photoacoustics.

Biomedical Optics Express, 2015
The lipid content in plaques is an important marker for identifying atherosclerotic lesions and disease states. Intravascular photoacoustic (IVPA) imaging can be used to visualize lipids in the artery.

Quantitative Photo-acoustic Tomography with Partial Data

, 2012
Photo-acoustic tomography is a newly developed hybrid imaging modality that combines a high-resolution modality with a high-contrast modality. We analyze the reconstruction of diffusion and absorption parameters in an elliptic equation and improve an ...

Photoacoustic Imaging of Epilepsy [PDF]

, 2010
Abstract : This research is aimed at developing a new imaging approach, called Photoacoustic tomography (PAT) , for non-invasively tracking dynamical changes during seizure occurrence. The project will develop imaging hardware and software, and conduct phantom/in vivo experiments to achieve the proposed goals.
