Description

Infrared Fluorescence Excitation Dye 808 is a specialized near-infrared (NIR) fluorophore designed for high-performance optical applications. Its core value lies in its strong absorption and efficient fluorescence emission in the 808 nm region, enabling deep tissue penetration and minimal background interference. This dye is essential for researchers and manufacturers in the fields of bioimaging, medical diagnostics, and advanced material science who require precise and stable NIR probes.

Application

• In Vivo Bioimaging and Diagnostics: As a contrast agent for fluorescence-guided surgery, tumor targeting, and non-invasive deep-tissue imaging in preclinical research.
• Optical Sensor Development: For constructing sensitive probes and biosensors that operate in the biological transparency window.
• Material Science and Photonics: Incorporation into nanoparticles, polymers, and coatings for applications in security inks, optoelectronic devices, and photodynamic therapy.
• Flow Cytometry and Cell Analysis: Used for labeling antibodies or other biomolecules in multiplexed assays requiring NIR detection channels.
• Chemical and Biological Research: As a versatile tool for studying molecular interactions, energy transfer processes, and environmental sensing.
