산화티타늄 나노 입자에 의한 실크 단백질 형광 증폭 연구

초록

We report a purely protein-based platform for green fluorescence by mixing silk protein with green fluorescence protein, and also report its enhancement by the incorporation of TiO2 nanoparticles. The TiO2 nanoparticles employed have diameters of 100 and 300 nm, with a significant increase in fluorescence (by a factor of 7.5) observed when introducing 300-nm TiO2 nanoparticles. Furthermore, an increase in particle distribution density is found to enhance fluorescence amplification. These research findings suggest that protein-based fluorescent films can be enhanced by the characteristics of nanoparticles, opening up new possibilities in the fields of optics and fluorescence applications.
