Fluorescent molecules that absorb and emit light in the near-infrared (NIR) and short-wave infrared (SWIR) regions have significant potential for various applications. These molecules can serve as ...

Ultrasound-switchable fluorescence (USF) imaging represents an innovative approach to overcoming the limitations imposed by optical scattering in deep biological tissues. By employing focused ...

Researchers used structured light and switchable fluorescent molecules to reduce the background light from the out-of-plane regions of microscope samples. This method allowed for the acquisition of ...

Redox-active triphenylamine-appended pyrazinacenes show extreme reversible redox-coupled switching of their photophysical properties. In their reduced state, absorption and emission bands fall well ...

A recent article published in Nature Communications explored an emission mechanism in bioactive polycysteine (PCys), an aliphatic polymer exhibiting high quantum yield, polymerization- and aggregation ...
