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 Based on Borenium Ions Could Improve Clearer Biomedical Imaging
MIT Develops Stable Red-Emitting Dyes for Better Biomedical Imaging Scientists at MIT have designed a new class of fluorescent molecules based on positively charged boron atoms, known as borenium cations, that glow in the red to near-infrared range. By stabilizing these ions with specially chosen ligands, the team has created materials that emit bright light…
