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 ...
31-Oct-2018
A team of researchers from the University of Illinois at Urbana-Champaign and Mayo Clinic have engineered a new type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is based on the conventional fluorescence in situ hybridization (FISH) ...
Modulating photo- and electroluminescence in a stimuli-responsive molecular dye
17-Aug-2018
Controlling the excited electronic states in luminescent systems remains a challenge in the development of fluorescent and phosphorescent dyes. Now, scientists in Japan have developed a unique organic fluorophore that changes its emission color without loss of efficiency when externally ...
Barcoding technique offers cost-effective alternative to current technology
17-Aug-2018
New technology developed by a team of McGill University scientists shows potential to streamline the analysis of proteins, offering a quick, high volume and cost-effective tool to hospitals and research labs alike. Proteins found in blood provide scientists and clinicians with key information on ...

In nature, proteins are assembled into sophisticated and highly ordered structures, which enable them to execute numerous functions supporting different forms of life. The exquisite design of natural proteins prompted scientists to exploit it in synthetic biology to engineer molecules that can ...
09-Jan-2017
In a microscopic feat that resembled a high-wire circus act, Johns Hopkins researchers have coaxed DNA nanotubes to assemble themselves into bridge-like structures arched between two molecular landmarks on the surface of a lab dish. The team captured examples of this unusual nanoscale performance ...
19-Aug-2016
When it comes to even the most advanced materials, the adage "if it does not bend, it breaks" is often true. But before that final snap, most materials experience microscopic damage that could be fixed -- but only if you know it's there. In a study researchers introduce a new technique that ...
