Development of personal biodosimeter of UV radiation based on vitamin D photosynthesis in nematic liquid crystal matrix
A new approach to the problem of personal UV biodosimeter is described. Nematic liquid crystal (LC-805) is converted into induced cholesteric phase using photosensitive chiral dopant of steroid biomolecules (7-dehydrocholesterol (provitamin D3) or 7-DHC-benzoate). Significant changes in optical char...

Significant changes in optical characteristics of the LC films depending on the duration of UV exposure are observed as a result of UV initiated photoisomerizations that change helical twisting power of dopant molecules. We would like to express our gratitude to Dr. Sofia Torgova (SSC of Russian Federation «NIOPIK») for helpful advice and generous gift of LC-805, and to Dr. Wolfgang Reischl (University of Vienna) for his help with synthesis of 7-dehydrocholesterol-Benzoate. en Інститут фізики напівпровідників імені В.Є.
