A molecular shield for near-infrared fluorescent dyes

Stable and Functional Dyes for Near-Infrared Fluorescence Imaging of Living Subjects

05-Jun-2020 - Scientists can monitor biomolecular processes in live tissue by noninvasive optical methods, such as fluorescence imaging. However, the fluorescent dyes used for that purpose are often rather unstable, and photobleaching, lack of specificity, and poor pharmacokinetics are recurrent issues. US ...

Tiny spiders, big color

15-May-2018 - There's plenty that's striking about Phoroncidia rubroargentea, a species of spider native to Madagascar, starting with their size - at just three millimeters, they're barely larger than a few grains of salt. But the reason they caught Sarah Kariko's eye had more to do with their color. Unlike ...

Fluorescence microscopy on a chip -- no lenses required

21-Sep-2017 - Fluorescence microscopy gives researchers incredible power to illuminate the tiniest structures and capture the real-time activities of live cells by tagging biological molecules with a veritable rainbow of fluorescent dyes. This power comes at a cost: The technology can be expensive and ...
