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 ...

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 ...

Ultrasound‐switchable fluorescence (USF) imaging combines the deep penetration and spatial selectivity of focused ultrasound with the high sensitivity and specificity of fluorescence detection. By ...

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 ...

Photobleaching is a general hurdle of fluorescence-based techniques especially in high-resolution microscopy that relies on prolonged and complex illumination. Strategies to reduce photobleaching ...
