Abstract

The ability to quantitatively and non-invasively detect nanoparticles in tissues has important implications on their development as an in-vivo cancer diagnostic tool. The Diffusion Reflection (DR) method is a simple, non-invasive imaging technique which has been proven useful for the investigation of tissue's optical parameters. We present a new method for the measurements of the GNR concentration in tissue-like phantoms based on DR measurements and the intense light absorption of gold nanorods (GNR). Monte Carlo simulations and tissue-like phantom measurements of the reflected light intensity are presented. The ability to extract the phantoms' optical properties and the GNR concentration in it from DR measurements was demonstrated.
