Description:

WARNING: This product is for research use only, not for human or veterinary use.

IR-1061 is a small-molecule organic dye belonging to the class of near-infrared II (NIR-II) fluorophores, emitting in the 1000–1700 nm range. It exhibits strong bioactivity as a contrast agent for deep-tissue imaging due to its excellent photostability, high quantum yield in the NIR-II window, and minimal background autofluorescence. IR-1061 operates through passive targeting mechanisms like the enhanced permeability and retention (EPR) effect, enabling high-resolution, noninvasive imaging in small animal models and offering potential for clinical translation in biomedical diagnostics.
