Red-emitting boron dyes could sharpen biomedical imaging
New red and near-infrared fluorophores promise sharper deep-tissue imaging Fluorescent imaging is a staple in biomedical research, helping scientists visualize cellular processes and diagnose diseases. Yet traditional blue and green dyes struggle to penetrate tissue, where scattering and autofluorescence obscure signals. Red and near-infrared (NIR) fluorophores offer a clearer window into deep tissues, tumors, and…

Red Fluorescent Dyes Bring Sharper Deep-Tissue Imaging
A Breakthrough in Red Fluorescent Dyes for Deep-Tissue Imaging Fluorescent imaging has long relied on blue and green dyes, which struggle to penetrate tissue and often clash with the body’s own autofluorescence. Red-emitting dyes have promised clearer, deeper views of biological structures, but have historically suffered from weak brightness and instability. A new class of…

Red Fluorescent Dyes Could Sharpen Biomedical Imaging of Tumors
Overview: A New Class of Red-Emitting Dyes Researchers at MIT have designed a novel family of fluorescent molecules based on borenium ions—positively charged boron-containing species—that emit light in the red to near-infrared (near-IR) spectrum. This work addresses a longstanding challenge in biomedical imaging: creating stable, bright dyes that emit in the red to near-IR region,…
