Dye that makes the skin transparent?

A commonly used yellow food dye known as tartrazine (E102) was applied to the abdomen of mice, making their internal organs visible through the skin: liver, intestines, etc.

After rinsing the dye, the skin returned to its previous state.

Similar tests have not been conducted on humans, but the first step towards a new, non-invasive method of diagnosing diseases has been taken.
