Stanford researchers make mice transparent using Doritos dye

Researchers at Stanford University have developed a method to make the skin of mice transparent using a solution containing yellow no. 5 food dye, also known as tartrazine, which is commonly found in Doritos. This innovative technique involved applying the dye to specific areas of the mice, such as their heads, abdomens, and hind legs. Within five minutes, the researchers were able to observe the underlying blood vessels, muscles, and organs in real-time, providing unprecedented insight into the anatomy of the mice. The process of achieving transparency is based on the principles of optics. Normally, skin is opaque due to the various cells and membranes that refract light, making it difficult for light to pass through. By using tartrazine, the researchers were able to reduce the refraction of light, allowing for a clearer view of the internal structures. Once the dye was washed off, the mice returned to their original opaque state, demonstrating the temporary nature of this transformation. This breakthrough has significant implications for medical science. If this technique can be adapted for use in humans, it could revolutionize the way medical conditions are diagnosed and treated. The ability to visualize internal structures without invasive procedures could enhance the precision of medical interventions, such as catheter placements and surgical operations. While the current findings are limited to mice, the potential applications in human medicine are vast. As researchers continue to explore this method, it may pave the way for new diagnostic tools and treatment strategies that could improve patient outcomes in various medical fields.
