Indocyanine green (ICG) is a near-infrared fluorescent dye. Protein-bound ICG can be excited by external light (750 ~ 810 nm) and emits near-infrared light (approx. 840nm). It has a blood half-life of 3-5 minutes, is absorbed by liver cells, and excreted through the biliary tract into feces.
Standard Improvement: Control limits for known impurities promote industrial standards.
Patent Protection: Authorized 4 Chinese and American invention patents for structure and synthesis.
Ambient Storage: Stored at room temperature without cold chain requirements, increasing accessibility.
Detection of choroidal neovascularization, macular lesions, and intraocular tumors. Helps physicians identify the capsule and internal limiting membrane more accurately.
Used for evaluation of liver reserve function and tumor localization. Enhances target visibility and improves surgical precision.
Including high-end medical devices (fluorescence imaging series), contrast agents (ICG), and core components (CMOS camera modules, endoscopes). Our products are used in over 500 large hospitals.
We focus on molecular fluorescence, Raman spectroscopy, and AI-assisted drug design. With 131 core invention patents and 7 US patents, we have established strategic partnerships with global leaders like B. Braun Melsungen and MITAKA.
