In this study, as a new functional addition to building materials using GFP genes was investigated. It was confirmed that the mixture of GFP did not affect the strength of plaster and gypsum within the range of this experiment. On the other hand, the fluorescent function was affected by the amount of GFP in the mixture, and the higher the amount of GFP in the mixture, the greater the intensity of fluorescence. It was also reconfirmed that the active pH range of GFP itself affected the fluorescent function.
