Researchers at Stanford University have found that a common food dye can temporarily render the skin, muscle, and other tissues of living animals transparent, enabling visibility into deeper biological structures like organs and blood vessels.
The technique could revolutionize medical diagnostics by allowing for non-invasive examination of tissues to identify injuries, draw blood efficiently, monitor digestive disorders, and detect tumors, potentially making procedures less painful.
Dr. Guosong Hong highlighted that this innovative approach simplifies the way deep-seated tumors are diagnosed, moving away from invasive biopsies to a method that simply involves examining the skin.
The researchers built upon the concept in HG Wells's The Invisible Man, theorizing that by altering the refractive index of tissues, certain dyes could allow light to penetrate and illuminate intricate biological structures.
