제목 Optical properties of the light-emitting biomaterial based on DNA-CTMA doped with riboflavin
초록 Deoxyribonucleic acid (DNA) is a remarkable biomaterial which has phosphate groups in the side chain, and it enables to react electrostatically with cationic surfactants and light-emitting materials. In this research, we suggest the optical gain medium based on salmon DNA biopolymer for biocompatible laser system. The deoxyribonucleic acid-cetyltrimethylammonium chloride surfactant (DNA-CTMA) doped with riboflavin has been measured by UV-vis spectroscopy and confirmed by photoluminescence measurement for the five different composition doping rates (100-2000 ppm of riboflavin) of the blended solution with hexafluoro-2-propanol (HFIP). The riboflavin-doped DNA-CTMA:HFIP solid-state thin-films are achieved by spin-coating method and the doping behavior has been studied by Raman spectroscopy.
