Cryo-imaging Breakthrough Reveals Thick Biological Structures with Greater Clarity
Overview: A New Window into Thick Biological Samples Cryo-imaging has long promised a clearer view of biological materials in their near-native state. Traditional electron microscopy, while superb for isolated molecules, struggles with thicker samples. A Cornell-led team has unveiled a transformative method—tilt-corrected bright-field scanning transmission electron microscopy (tcBF-STEM)—that delivers higher contrast and dramatically increased efficiency…

Red Fluorescent Dyes: A Breakthrough for Deep-Tissue Biomedical Imaging
Overview: A new class of red-emitting fluorescent dyes Biomedical imaging often relies on fluorescent dyes to illuminate structures inside tissues. Traditional blue and green dyes face two major challenges: light scattering in tissue and interference from endogenous signals, which reduces image clarity at depth. Red and near-infrared (NIR) emissions offer a solution because they penetrate…

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…
