🟢The crystal structure of the green fluorescent protein, GFP! 🟢
The chromophore is yellow. The protein rigidizes the chromophore, releasing energy as fluorescence.
🎥I made the movie with UCSF Chimera & 1EMA.pdb.

🦂The haunting scorpion fluorescence! 🦂
The scorpions are embedded in resin. Fluorescence is produced with ultraviolet light, but most wavelengths produce fluorescence. We use them to test animal and wide-field fluorescence imagers.

🔹🔷Fluorite Fluorescence!🔷🔹
George Stokes coined "fluorescence" in 1852 after fluorite, which glows blue under UV light. Fluorite is CaF2. Fluorescence is usually caused by yttrium, europium, or samarium impurities.

Today, I would like to honor the memory of Roger Y. Tsien, born on February 1, 1952. His legacy lives with all who use his technologies, including calcium sensors, fluorescent proteins, the acetoxymethyl (AM) ester, & many more! #FluorescenceFriday

✨💃Disco Ball!💃✨
A UV laser excites fluorescein, producing green fluorescence. Glitter scatters the light to demonstrate dynamic light scattering (DLS) for measuring particle size.
