Professor Park's team developed a supramolecular photocatalyst that can transfer electrons similar to chlorophyll in nature by modifying rhodamine, an existing fluorescent dyes, into an amphiphilic structure.

Crews started dumping the rhodamine dye into the water Monday and will complete the study by Friday, according to a news release.

The team was also able to devise several new ways to make classic rhodamine dyes, enabling them to create dozens of functional versions relatively quickly.

While this isn't the end of the story for rhodamine dyes, the work is likely moving in a different direction.

Four of the researchers on the most current publication were also on the very first rhodamine dye paper the lab published, in 2011.
