New Fluorescent Dyes Could Advance Biological Imaging, Howard Hughes Medical Institute Study

Swapping out specific chemical building blocks in fluorescent molecules called rhodamines can generate nearly any color scientists desire -- ROYGBIV and beyond, researchers report September 4, 2017 in the journal Nature Methods.

The work offers scientists a way to adjust the properties of existing dyes deliberately, making them bolder, brighter, and more cell-permeable too.
