Photoacoustic flow cytometry [PDF]
Methods, 2012 Conventional flow cytometry using scattering and fluorescent detection methods has been a fundamental tool of biological discoveries for many years. Invasive extraction of cells from a living organism, however, may lead to changes in cell properties and prevents the long-term study of cells in their native environment.

Nanoparticles for photoacoustic imaging [PDF]
WIREs Nanomedicine and Nanobiotechnology, 2009 AbstractNanoparticles have been designed and applied as contrast enhancers in various optical imaging techniques, such as optical coherence tomography, fluorescence imaging, and optical reflectance microscopy. As an emerging hybrid imaging modality, photoacoustic imaging (PAI) has also benefited from the application of these nanoparticle‐based contrast

Photoacoustic ocular imaging [PDF]
Optics Letters, 2010 We developed a photoacoustic ocular imaging device and demonstrated its utility in imaging the deeper layers of the eye including the retina, choroid, and optic nerve. Using safe laser intensity, the photoacoustic system was able to visualize the blood distribution of an enucleated pig's eye and an eye of a living rabbit.

Thermal Resistance of 1D Micron‐Wide Interface Under External Force Modulation
Advanced Materials Interfaces, EarlyView.A novel TET‐based technique is developed to characterize the interfacial thermal resistance at the microscale. The interfacial thermal resistance is measured at ≈1200–1400 mK/W for natural contact. Externally applied force reduces the thermal resistance dramatically down to ≈125 mK/W.

Photo-acoustic tomography in a rotating setting
, 2019 Photo-acoustic tomography is a coupled-physics (hybrid) medical imaging modality that aims to reconstruct optical parameters in biological tissues from ultrasound measurements. As propagating light gets partially absorbed, the resulting thermal expansion

Commentary on Photoacoustic Tomography [PDF]
Journal of Nuclear Medicine, 2015 Substantial funding, notably from the National Cancer Institute of the United States, over the past 10 y has greatly promoted noninvasive approaches to studying pathophysiology, tumor progression, and response to therapy as well as pharmacokinetics and biodistribution of potential therapeutics ...

Advanced Photonics Research, EarlyView.Extreme miniaturization of Fabry–Perot cavities has severe impacts on their spectral response and spatial distribution of the resonant modes. A fully analytical methodology is proposed accounting for the finite borders of the micromirrors to predict this behavior. Model validation relies on comparing with measurements obtained on silicon micro‐cavities
