Doritos might be known for spicing up snack time, but Stanford researchers have discovered that a dye in the chips can also turn mice translucent.
The study, published on Sept. 6 in the journal Science, explains how researchers at Standford University in California, used a common food dye called Yellow No. 5 — found in various foods and beauty products — on the skin of live mice.explains how researchers at Stanford University in California used a common food dye called Yellow No. 5 — found in various foods and beauty products — on the skin of live mice.
The technique, called “optical tissue clearing,” which has not yet been tested on humans, could potentially allow the non-invasive observation and monitoring of injuries or diseases, the authors argue.
To make bodies transparent, scientists wanted to make all the different parts of the tissues have the same light-bending properties.Destroy old COVID shots to get new ones? What’s behind the guidanceWhen this dye is added to water and soaked into tissue, tartrazine molecules are structured in a way that aligns with the light-bending ability of the skin. The dye absorbs blue and purple light and allows red and orange light to travel through the tissue, resulting in transparency, the study said.
“Strongly absorbing dye molecules, when applied topically to biological tissues, can reduce the intrinsic light scattering within these tissues,” the study said. “This effect renders various biological tissues –including the scalp, muscle, and abdomen — transparent.”After rinsing off the dye, the tissues quickly returned to their normal opacity, the researchers said, adding that tartrazine did not seem to have any lasting effects.about the study, Christopher J.
