Effects of ICG concentration on the optical properties of erythrocyte-derived nano-vectors
Abstract
Erythrocyte-based nanoparticle platforms can offer long circulation times not offered by traditional drug delivery methods. We have developed a novel erythrocyte-based nanoparticle doped with indocyanine green (ICG), the only FDA-approved near-infrared chromophore. Here, we report on the absorption and fluorescence emission characteristics of these nanoparticles fabricated using ICG concentrations in the range of 161-323 μM. These nanoparticles may serve as biocompatible optical materials for various clinical imaging and phototherapeutic applications.
