Octopus Probe Developed for High-Performance NIR-II Cancer Imaging
Researchers have developed a novel molecular imaging probe named "Octopus" (OCTP) to enhance the precision of intraoperative tumor resection, a critical yet challenging aspect of cancer treatment. Published in the Proceedings of the National Academy of Sciences, this study introduces a modular near-infrared II (NIR-II) fluorescence probe operating at wavelengths greater than 1,300 nm. The OCTP probe specifically targets the folate receptor, which is commonly overexpressed in various cancer types. Comparative analysis indicates that OCTP exhibits superior performance characteristics compared to Cytalux, a currently used clinical probe. By leveraging the deeper tissue penetration and reduced scattering associated with NIR-II imaging, Octopus aims to provide surgeons with clearer, high-contrast visualization of tumor boundaries during surgery. This technological advancement holds significant potential for improving surgical outcomes by ensuring more complete tumor removal while sparing healthy tissue. The development represents a notable breakthrough in biomedical optics and oncological surgery, offering a promising tool for next-generation image-guided interventions. The findings underscore the importance of advanced molecular imaging technologies in addressing the limitations of current standard-of-care procedures in oncology.
