Target
ICG
Molecular classification
Small molecule, Tricarbocyanine dye, Contrast Agent, Fluorophore
01

Overview

Indocyanine green (ICG) is a water-soluble, tricarbocyanine fluorescent dye widely used in medical diagnostics. It is primarily utilized as a non-targeting contrast agent for optical imaging. It binds tightly to plasma proteins after intravenous administration and remains confined within the vascular system. It has a short half-life and is exclusively removed from circulation by the liver into bile without undergoing metabolism.
