The distinctive spectral absorption characteristics of cancer cells make photoacoustic techniques useful for detection in vitro and in vivo. Here we report on our evaluation of the photoacoustic signal produced by a series of monolayers of different

Recently, we introduced laser-induced sound pinging (LISP) as a simple photoacoustic technique for the expedient and fairly rapid (2–3 min) measurement of the speed of sound traversing low-volume samples (25–1000 μL), built around an inexpensive

We recently reported on fixed-path length laser-induced sound pinging (FPL-LISP) as a rapid photoacoustic technique employing an inexpensive benchtop tattoo-removal laser for reliably determining the speed of sound in low-volume fluids. In this contr

When thermal and stress confinement conditions are satisfied, the propagation of laser-induced ultrasound (LIU) is governed by an inhomogeneous wave equation for pressure, and the laser temporal profile can be modeled by a Dirac delta distribution. I
