BNUZH-China is a very excellent and friendly team, with infinite creativity and passion. This year, our team consists of 18 students from different subjects, three excellent advisors, and six experienced teachers. Our love of synthetic biology has brought us together. This year's project (BCAID) is very creative and challenging. We have tried to build a BC composite scaffold with living cells to assist in the healing of large skin wounds, which is unprecedented in the iGEM competition, and is prospective even in the entire related research field. The design and construction of BCAID was very difficult. We encountered many unexpected difficulties, but thanks to the persistence of the students and the help of the teachers, we finally completed the project successfully!
