Fiber endface photoacoustic generator for quantitative photoacoustic tomography
Optics Letters, 2021 We demonstrate a novel fiber endface photoacoustic (PA) generator using infrared (IR) 144 laser dye dispersed within an ultraviolet adhesive. The generator provides a wide acoustic bandwidth in the transducer frequency range of 2–7 MHz, high thermal conversion efficiency ( > 90 % ), good PA signal controllability (well ...

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.
