| Description | ICG-carboxylic acid is a fluorescent probe in the near-infrared (NIR) range. It is derived from indocyanine green (ICG), a commonly used fluorescent dye in medical diagnostics. ICG exhibits a peak absorption at 800 nm, allowing it to efficiently absorb energy from near-infrared lasers and release heat within the dyed tissue. |
| In vitro | Indocyanine green (ICG) is a water-soluble compound that is widely and safely used in medical diagnostics for its well-established fluorescence properties. It has been used in fluorescence-guided surgery to identify critical structures, including intra-abdominal tumors[1]. |
