According to the principle of restoring murals, we also try to repair works of art with similar material structures such as oil paintings, that saves the manpower and resources needed to train talents. The use of pigment protein painting on the culture medium gave us an inspiration, not only in the field of restoration of cultural relics, DH5α may become a new form of modern art creation, providing modern art with different creative materials and patterns, and the sense of age brought by the mineralized texture allow artists to have more ways to show the ancient meaning in history. DH5α between modern and ancient times, the combination of innovation and tradition, when appreciate the works of art, peoples learn more about the value behind art and the treasures of our Chinese traditional culture. By far, DH5α can only achieve mineralization for one color by utilizing amilCP. However, the structure of amilCP, which the production of the pigment depends on, changes over time. Therefore, for the future experiment, we hope to use compounds to produce pigments so that their colors can be more consistently preserved. During the experiment, we found that current mineralization technology is preliminary. When reading Engineering RGB Color Vision into E.coli[1], we considered that RGB lights can be appended as control system and by changing genes to achieve more accurate mineralization, the efficiency of repairing is faster by using projection equipment. Moreover we read a paper by Zhong Chao's team that explained that mineralized biofilms can be used as programmable and 3D printable biofilm functional materials[2]. These living materials can not only be directly 3D printed by themselves, but also can be mixed with quantum dots. The printed living material in the hydrogel can sense the external signal in the solution and emit fluorescence, which can be used as a biosensor. As a living material, even after long-term storage, it still has the characteristics of self-regeneration. This also provides a wider range of ideas and applications for our projects.
