Optical Clearing for OCT Image Enhancement and In-Depth Monitoring of Molecular Diffusion

In this paper, we overview the basic principles, recent results, advantages, limitations, and future of the optical clearing method in application to many fields of biology and medicine. We also discuss the possibility of noninvasive assessment of molecular diffusion in tissues using the optical coherence tomography technique. Issues of safety and toxicity of application of different endogenous and exogenous molecules to tissues are outlined.
