Fluorescence quenching is a critical process in photophysical and photochemical studies, describing the reduction in a fluorophore’s emission intensity due to interaction with a quencher. In systems ...

In recent years, fluorescence quenching microscopy (FQM) 1-3 has emerged as a viable technique that allows for the swift, cost-effective, and accurate imaging of two-dimensional (2D) materials like ...

A lab developed a single-atom switch to turn fluorescent dyes used in biological imaging on and off at will. It only took the replacement of one atom for Rice University scientists to give new powers ...

Auxin is a hormone crucial in nearly every aspect of plant growth and development. Advancing our understanding of auxin signaling in maize and other crop plants may provide needed tools for ...

A single-molecule imaging technique, called protein-induced fluorescence enhancement (PIFE), has gained traction in recent years as a popular tool for observing DNA-protein interactions with nanometer ...

In addition to endogenous autofluorescence, scientists must also contend with obfuscating signals introduced during the experimental workflow. This non-specific signal can come from multiple sources, ...

Scientists use simulations to understand the mechanism behind a popular fluorescent protein used to monitor signals between neurons. Their work could lead to a practical screening tool for designing ...

Using a strategy that should be applicable to many fluorescent dyes, chemists have created the brightest-ever fluorescent materials. The approach combines commonly available cationic dyes and a ...

Researchers have developed a simple method for making fluorescent dyes of many colors that can be activated by visible light. The method involves switching out a single oxygen atom in existing ...
