#Mice made transparent with a #dye used in #Doritos
Stanford scientists has found an agent that can reversibly make skin transparent without damaging it. #Tartrazine, a popular yellow-orange food dye called FD&C Yellow 5 is notably used for coloring Doritos. Hong’s team dissolved the dye in an aqueous solution and created a transparency-inducing lotion of sorts. It worked, because the dye reduced the difference in refractive index between water and lipids in the skin.

Matching refractive indexes lets some wavelengths pass cleanly through the skin.

In case anyone was following the recent Science paper about using Tartrazine for #tissueclearing, apparently there is at least one (competing) group that couldn't reproduce it and wrote a preprint about it:

Tartrazine cannot make live tissues transparent
