Publikováno v: Dynamics and Fluctuations in Biomedical Photonics XVIII.

Optical clearing (OC) increases the depth of light penetration and improves the outcomes of optical imaging measurements in situ and in vivo. In vivo OC protocols have to be biocompatible and should result in transient effects with minimal long-term
