We report a purely protein-based platform for green fluorescence by mixing silk protein with green fluorescence protein (GFP), and also report its enhancement by the incorporation of TiO 2 nanoparticles. The TiO 2 nanoparticles eployed have diameters of 100 and 300 nm, with a significant increase in fluorescence (by a factor of 7.5) observed when introducing 300-nm TiO 2 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.
