Indocyanine Green (ICG) is a cyanine dye with near-infrared fluorescence properties. It is utilised in advanced materials engineering, mainly through encapsulation in nanocarriers like halloysite nanotubes (HNTs) to enhance photostability for photothermal therapies and antimicrobial coatings. It is loaded into HNT-ICG nanohybrids and electrospun into polyacrylonitrile (PAN) nanofibers to enable rapid NIR light-activated heating up to 79.3 degree Celsius within two minutes, achieving a 7-log reduction in Staphylococcus aureus bacteria on surfaces.

This function makes it ideal for scalable production of light-triggered antibacterial textiles, wound dressings, and medical device coatings. Additionally, beyond biomedical uses such as fluorescence-guided surgery and tissue perfusion imaging, these stabilised ICG formulations support broader industrial innovations in photothermal nanomaterials for remote-activated heating in composites.

The market demand for Indocyanine Green (ICG) is propelled by rising demand for minimally invasive surgeries, advancements in near-infrared fluorescence imaging technologies, and expanding applications in ophthalmology, neurosurgery, and liver disease diagnostics. The increasing prevalence of chronic conditions like eye and liver diseases, as well as R&D innovations in cancer detection, lymphatic mapping, and intraoperative imaging, also boosts the market. Additional drivers for the Indocyanine Green (ICG) market include the growing integration of ICG in robotic-assisted surgeries and endoscopy procedures, fuelled by its real-time visualisation capabilities that enhance precision and reduce operative times.

Additionally, increasing investments in nanomedicine R&D for ICG-based photothermal and photodynamic therapies against cancer further accelerate demand, as well as regulatory approvals expanding its use in paediatric cardiology and sentinel lymph node biopsies. However, regulatory factors such as GMP approval, full traceability of batches, production dates, and storage conditions impact industrial indocyanine green procurement due to ICG's sensitivity to light and moisture degradation.

Raw Material for Indocyanine Green Production

According to the Indocyanine Green production plant project report, the various raw materials for Indocyanine Green production include 1,1,2-trimethyl-1H-benzo[e]indole and 1,4-butane sultone.

Production Process of Indocyanine Green

The extensive Indocyanine Green production cost report consists of the following major industrial production process:

1. Production via chemical synthesis: The production process of Indocyanine Green (ICG) involves four main steps. In the first step, 1,1,2-trimethyl-1H-benzo[e]indole is heated with 1,4-butane sultone at 120 degree Celsius to form a cationic heterocyclic compound. In the second step, refluxing 1-chloro-2,4-dinitrobenzene with pyridine in acetone gives N-(2,4-dinitrophenyl)pyridinium chloride (Zincke salt). The third step involves reacting the salt with aniline in ethanol to obtain N,N′-diphenylbut-2-ene-1,4-diamine monohydrochloride. Finally, condensing cationic heterocyclic compound and N,N′-diphenylbut-2-ene-1,4-diamine monohydrochloride with sodium acetate and acetic anhydride at 110 degree Celsius produces ICG as a green powder. Additionally, each step involves solvent removal and purification by filtration and washing to afford the respective intermediates and the final product in good yields.

Properties of Indocyanine Green

Indocyanine Green (ICG) is a water-soluble tricarbocyanine dye with the molecular formula C43H47N2NaO6S2 (sodium salt) and a molecular weight of 774.97 g/mol. It appears as a dark green to light yellow-amber powder or crystal, with peak absorption at 785-800 nm (in ethanol or water) and fluorescence emission around 820 nm, enabling near-infrared imaging. It has low bioavailability, high polar surface area (117-120 Ų), 14 rotatable bonds, six rings, and sensitivity to light/moisture degradation, while being slightly soluble in water and pH-insensitive.
