Abstract:Photoacoustic imaging (PAI) is a rapidly growing imaging modality, which combines high contrast of optical absorption with deep penetration depth of ultrasound. When combined with endogenous contrast agents based on light-absorbing nanoparticles (NPs), PAI can visualize various biological processes and tissues. Here, we describe a simple experimental setup based on a tissue-mimicking phantom with flexible optical properties for studying photoacoustic (PA) response of NPs. Our approach is based on a polyacrylam… Show more
