Abstract
In this work, we used the laser-ablated Titanium Nitride (TiN) nanoparticles as an exogenous contrast agent for lab-made PAM (Photoacoustic Microscopy) and PAT (Photoacoustic Tomography). The absorption spectra of the 50-100 nm-sized TiN nanoparticles confirmed the presence of a broad plasmonic band covering both parts of the visible and near-infrared (NIR) spectrum. The PAM system was used to image the TiN nanoparticles with a resolution of ~ 50 µm, underneath 1 mm chicken breast tissue. For the PAT results, lower resolution (~ 400 µm) was measured, but the penetration depth of 2 cm was observed.
