Paper Abstract

Fluorescent molecular probes offer a potential for early cancer detection. Indocyanine green (ICG) is an FDAapproved near-infrared (NIR) fluorescent dye used in ophthalmic angiography and assessment of cardiac and hepatic functions. However, clinical applications of ICG remain very limited due to its rapid clearance from vascular circulation, unstable optical properties, non-specific interactions with plasma proteins, and inability for localized targeting. To overcome these limitations, we have encapsulated ICG within nanoconstructs composed of poly(allylamine) hydrochloride and disodium hydrogen phosphate salt. To understand the effects of coating materials on the cellular uptake of the nanocapsules, we have measured the uptake of ICG-loaded nanocapsules (ICG-NCs) with various coating materials by HeLa cancerous cervical epithelial cells in-vitro. Results of this study provide important information for the choice of appropriate coating materials that will result in maximal uptake of ICG-NCs in optical and phototherapy of cancerous tissue.
