Scientists have found a way to temporarily make the skin of mice transparent using common food coloring. The team, led by Zihao Ou, an assistant professor of physics at the University of Texas at Dallas, applied a solution containing the yellow food dye tartrazine to the skulls and stomachs of live mice. This made it possible to observe the internal organs and blood vessels of the animals without surgical intervention. After the dye solution was removed, the skin normalized without harming the mice.
Optical physics behind the process
Skin transparency to water and FDandC yellow. The value 5 is achieved by combining tartrazine food coloring. The dye changes the refractive index of the skin and lets light through more easily, reducing light scattering. This process allows you to see the skin and see the mist dissipate.
Control of the functioning of the organs and the brain
The researchers used the dye to trace the blood vessels under the skull, the internal organs of the mouse, and the abdominal muscle contractions. The procedure does not require incisions or physical damage to the skin or bones, making it an excellent tool for biomedical research. Transparency is created in minutes, similar to how face creams work by distributing molecules in the skin.
Future applications of technology
This breakthrough will revolutionize fields such as biomedical imaging and healthcare by providing non-invasive ways to view the body’s internal systems. If successful in humans, it could be used in medical procedures such as blood draws to make veins more visible. A Stanford University study shows significant progress in medical research.
