Scientists Develop Method to Make Mice Partially Transparent Using Food Dye

Stanford researchers achieve breakthrough in biomedical imaging by applying tartrazine to rodents, revealing internal structures without surgery.

Tartrazine, a common food dye, makes mouse skin temporarily transparent when applied topically.
The dye alters the skin's refractive index, allowing light to pass through and revealing blood vessels and organs.
The procedure is non-invasive, reversible, and does not harm the mice.
Potential future applications include non-invasive diagnostics and improved medical imaging for humans.
The technique could revolutionize biomedical research by providing a new way to study living tissues.
