Editor’s summary
Optical imaging of biological tissues is hindered by the scattering and, to a lesser extent, absorption of light that limits the penetration depth. Ou et al. addressed this problem through an approach that at first may seem counterintuitive: the introduction of highly absorbing molecules (see the Perspective by Rowlands and Gorecki). The authors show that the addition of common dye molecules that absorb in the near ultraviolet and blue regions improve optical transparency in nearby longer wavelengths. In essence, by causing sharp absorption in the blue region, the refractive index in the red part of the spectrum is increased without increasing absorption. The addition of tartrazine was able to make the skin of a live rodent temporarily transparent. —Marc S. Lavine
