In what might be a bit of nightmare fuel. Scientists at Stanford have made skin transparent enabling the direct optical study of internal organs in live mice.
We report on the counterintuitive observation that strongly absorbing molecules can achieve optical transparency in live biological tissues. Specifically, we found that an aqueous solution of a common food color approved by the US Food and Drug Administration, tartrazine, has the effect of reversibly making the skin, muscle, and connective tissues transparent in live rodents.
