    Biological Auto(chemi)luminescence Imaging of Oxidative Processes in Human Skin

  • Original language description

    Oxidative processes in all types of organisms cause the chemical formation of electronically excited species, with subsequent ultraweak photon emission termed biological auto(chemi)luminescence (BAL). Imaging this luminescence phenomenon using ultrasensitive devices could potentially enable monitoring of oxidative stress in optically accessible areas of the human body, such as skin. Although oxidative stress induced by UV light has been explored, for chemically induced stress, there is no in vivo-quantified imaging of oxidative processes in human skin using BAL under the controlled extent of oxidative stress conditions. Furthermore, the mechanisms and dynamics of BAL from the skin have not been fully explored. Here, we demonstrate that different degrees of chemically induced oxidative stress on the skin can be spatially resolved quantitatively through noninvasive label-free BAL imaging. Additionally, to gain insight into the underlying mechanisms, a minimal chemical model of skin based on a mixture of lipid, melanin, and water was developed and used to show that it can be used to reproduce essential features of the response of real skin to oxidative stress. Our results contribute to novel, noninvasive photonic label-free methods for quantitative sensing of oxidative processes and oxidative stress.
