The Design, Synthesis, and Photophysical Properties of a Novel NIR-11 Dye for Biological Imaging and Optoelectronic Devices

Description:

Overview of Technology

The NIR-II Dye is a novel emissive material that has been developed to absorb and emit light in the NIR-II region. 

Background

Current technologies rely on inorganic materials to emit light in the spectral region, which are hard to clear from biological systems and have poorly defined structures at an atomic level. However, the NIR-II Dye would be the only stimuli responsive organic material in this region and can potentially allow real time during surgery and laser imaging.

Description of Technology 

This technology introduces a rare example of a well-defined organic structure which may clear biological systems and can have excellent quality control. This fluorescence-based dye enhances optical imaging and devices and has great commercial potential for companies in the Biomedical Industry that seek to improve biological imaging and testing.

NIR-II Dye is a novel emissive material that has been designed to absorb and emit light in the NIR-II region where humans are most transparent. This dye can also be adjusted to the short-wave infrared (SWIR) region where telecommunication and night vision options are non-existent with organic materials. This allows for a dramatic advantage in operating under atmospheric conditions relative to current inorganic materials used that require nitrogen cooling to work. Current technologies rely on inorganic materials to emit light in the spectral region, which are hard to clear from biological systems. However, the NIR-II Dye would be the only stimuli responsive organic material in this region and can potentially allow real time during surgery and laser imaging. The stage of development for this technology is at the Research Prototype Stage or TRL 4.

Benefits

The Near Infrared (NIR) II Dye allows for a more direct, real-time laser imaging of biological samples at a faster, more affordable rate than an MRI.

Applications

The biomedical industry or any market seeking to improve biological imaging and testing would be benefited from this NIR‑II Dye. This dye may also be used in night vision sensing, broadened solar cell spectral use, and can be used for secure NIR Organic Light-Emitting Diodes (OLED) displays. Mississippi State University seeks licensees for a technology that allows for an organic way to emit light in theNIR-II spectral region.
