Author Affiliations +
Our first steps towards nanoparticle assisted, optical molecular imaging (NAOMI) using OCT as the imaging modality are presented. We derive an expression to estimate the sensitivity of this technique. We propose to use nanoparticles based on biodegradable polymers, loaded with suitable dyes as contrast agent, and outline a method for establishing their desired optical properties prior to synthesis. This report presents preliminary results of our investigation on the use of nanoshells to serve as contrast agents We injected nanoshells with specific contrast features in the 800 nm wavelength region in excised porcine eyes. The nanoshells showed up as bright reflecting structures in the OCT images, which confirm their potential as contrast agents.
